Before You Buy: A Third-Party Inspection Is Your Only Real Leverage

Foretravel Unicoach rigs are complex, often 20–30 years old, and many have been customized or remodeled. Hidden defects may not surface during a quick dealer walkthrough or a private seller’s demonstration. Arrange an independent, certified RV inspection before purchase—full chassis, house systems, air systems, and moisture scans. A thorough inspector should do air-leak tests, hydronic heat operational checks, thermal imaging for water intrusion, roof membrane/edge assessments, and load testing on batteries and inverters.

• Why now, not later: Before money changes hands is your leverage window. After signing, many buyers report their coach sits at the dealer for weeks or months awaiting parts or approval, cancelling trips and compounding costs.
• Find inspectors: Start with a local query: RV Inspectors near me. Ask specifically for diesel pusher experience and hydronic heat expertise.
• Put it in writing: Make the sale contingent on passing an inspection and test drive, with a punchlist of defects the seller must remedy or price reductions applied.

Structural and Body Issues Reported by Owners

Roof seams, cap transitions, and water intrusion

While Foretravel’s construction is widely regarded as robust, aging sealants and roof-to-cap transitions are chronic concerns across older premium coaches. Owners report resealing needs at front/rear caps, clearance lights, and roof penetrations. Water intrusion—even slow—can rot substructures and delaminate wall sections over time. Window frames and marker lights are frequent leak points noted on forums and in video diaries.

• Look for soft spots in the ceiling and wall waviness—especially around slide openings on later Unicoach variants.
• Inspect the fiberglass roof edges where the radius meets sidewalls; UV and flexing can open hairline gaps.
• Verify previous owner maintenance logs for regular reseal cycles.

Research real-world owner threads: Google: Foretravel Motorcoach Unicoach Water Intrusion and YouTube: Foretravel Motorcoach Unicoach Roof Leaks.

Dual-pane window fogging and frame failure

Fogged thermopane windows are extremely common on older high-end coaches, including Unicoach models. Lost seals lead to condensation and reduced visibility. Replacement or rebuild costs escalate quickly with custom sizes and egress requirements.

• Budget $350–$1,000 per window depending on size and labor access.
• Inspect carefully around the driver’s and passenger’s side for safety-critical sight lines.

Chassis, Suspension, and Braking Complaints

Air system leaks, leveling failures, and ride-height issues

Air-suspension coaches live and die by the integrity of their air systems. Owners of older Unicoachs report slow-to-moderate air leaks that cause overnight coach settling, hissing at fittings, and unreliable leveling. Air dryer neglect can accelerate valve/fitting contamination. An air leak is not just a convenience issue—it can become a safety problem if brake system pressure drops below safe thresholds or if ride height changes unexpectedly while moving.

• Insist on a leak-down test. A qualified inspector should isolate chassis vs. house air consumption and test ride-height valves.
• Visually inspect bags for dry rot and cracking; replace in sets.
• Confirm compressor and dryer service history; desiccant cartridges should be on a regular schedule.

Owner threads frequently discuss this: Google: Foretravel Motorcoach Unicoach Air Suspension Problems.

Steering wander and tag-axle alignment

Older coaches can exhibit steering wander at highway speeds due to worn bushings, alignment drift, or worn steering gear. Tag-axle alignment issues manifest as abnormal tire wear and subtle “push” during lane changes. Owners report needing specialty alignment shops comfortable with heavy Class A buses.

• Test drive at highway speed and in crosswinds if possible. Note corrections needed to track straight.
• Review recent alignment sheets; verify caster/camber/toe values are in spec for the specific chassis revision.

Powertrain, Cooling, and Drivetrain

Engine cooling, fan clutch, and exhaust system leaks

High-mileage diesel engines (often Cummins on these coaches) are robust but not immune to age-related failures. Owner narratives include radiator core leaks, charge-air-cooler deterioration, fan hub/clutch failures that cause overheating under load, and exhaust manifold cracks. Overheating events can cascade into head gasket or turbocharger damage if not addressed quickly.

• Demand oil analysis and cooling system pressure testing before purchase.
• Examine service records for radiator or CAC replacement. Verify proper coolant type and change intervals.

Allison transmission service, retarder quirks, and sensors

Allison transmissions are respected, but proper fluid (e.g., TES 295–approved) and filter service intervals are critical. Some owners report shift hesitation, sensor faults, or retarder performance inconsistencies on steep descents if service is neglected. Repairs can be costly.

• Pull transmission diagnostics for codes; insist on fluid sample reports.
• Verify retarder operation during a test drive on a safe grade.

Owner discussions: Google: Foretravel Motorcoach Unicoach Transmission Problems.

Electrical and House Systems Defects

Inverter/charger failures and shore/gen transfer issues

Electrical complaints range from inverter/charger failure (older Trace/Xantrex units) to automatic transfer switch arcing. Owners report intermittent 120V outages, tripped GFCIs, and shore-to-generator switchover hiccups. These faults can mask deeper wiring problems in legacy coaches.

• Inspect transfer switch for heat discoloration and wire torque.
• Load-test house batteries and confirm correct charging profiles.

Cross-verify with owner reviews: RVInsider: Foretravel Motorcoach Unicoach Electrical Problems.

12V wiring gremlins and parasitic draws

Decades-old wiring, splices, and aftermarket add-ons lead to phantom draws, flickering lighting circuits, and hard-to-diagnose control issues. Owners mention hours of tracing to find a mis-crimped butt connector or a failing relay hidden behind a panel.

• Have an inspector conduct parasitic draw tests with circuits isolated.
• Document any owner-installed modifications and assess workmanship.

Forum chatter: Good Sam Community: Foretravel Motorcoach Unicoach Electrical Issues.

Generator (Onan Quiet Diesel) service and fault codes

Generators see heavy loads in luxury coaches. Common complaints include hard starts, shutdowns under load, cooling system leaks, and control board faults. Neglecting exercise and coolant changes accelerates wear.

• Run the generator at 50–75% load for at least 30 minutes during inspection; verify output and temps.
• Check for service bulletins and hours versus age.

Owner reporting: YouTube: Foretravel Motorcoach Unicoach Generator Problems.

Heating, Cooling, Plumbing, and Appliances

Hydronic heat (Aqua-Hot/Hydro-Hot) leaks, soot, and burner faults

Hydronic systems deliver luxury comfort but demand maintenance. Reports include glycol leaks, burner nozzle carboning, failed circulation pumps, and diesel burner lockouts. Heat exchanger leaks can produce fumes or damage nearby components. In cold climates, a nonfunctional hydronic system can make a coach unlivable.

• Inspect for dampness around the boiler bay, check for soot streaks at the exhaust, and confirm proper heat at all zones.
• Ask for recent service invoices for burner tune-ups and pump replacements.

Owner threads and videos: Google: Foretravel Motorcoach Unicoach Aqua-Hot Problems.

Roof A/C performance and ducting inefficiencies

As compressors age, owners report marginal cooling at high ambient temps, thermostat sensor drift, and loud operation. Some coaches have inconsistent ducting that leaves hot zones.

• Measure delta T at vents; test all fan speeds; verify clean coils and filters.

See related reports: Good Sam Community: Foretravel Motorcoach Unicoach AC Problems.

Plumbing leaks, tank sensors, and macerator failures

Owners often complain of inaccurate tank sensors, pump cycling due to minor leaks, and macerator clogs. Flexible lines harden with age and fittings can drip undetected into compartments.

• Pressure test plumbing, inspect under sinks and at the water heater for mineral deposits and slow leaks.
• Cycle every valve and confirm macerator operation under supervision.

After-Sale Support, Parts Availability, and Service Delays

Parts sourcing for legacy Unicoach models

For older Unicoach models, owners frequently cite long waits for proprietary parts or the need to retrofit third-party components. Specialty glass, body panels, and certain chassis elements can be scarce or require custom fabrication, elongating repair timelines and costs.

• Ask the seller for a parts source list and confirm availability for known wear items.
• Expect potential downtime; plan travel accordingly or negotiate price to reflect future repairs.

See patterns in complaints databases: BBB search: Foretravel Motorcoach Unicoach and Google: Foretravel Motorcoach Unicoach Parts Availability.

Warranty, goodwill, and dealer service prioritization

Warranty coverage is typically irrelevant for most Unicoach units due to age, leaving owners reliant on goodwill or paid service. Multiple consumers complain that once payment clears, they’re “in the line” with little control, leading to month-long waits—especially during peak seasons. Some dealers prioritize new sales customers.

• Negotiate service commitments before sale or work with an independent shop with a diesel pusher track record.
• Document all communication and timelines; escalate politely but persistently if delays mount.

Balanced Note: Reputation vs. Age and Complexity

Foretravel’s craftsmanship is often praised relative to mass-market RVs. Many Unicoach units have served for decades with loyal followings. However, age and complexity are unforgiving. Even well-built luxury coaches develop expensive, layered problems—particularly those involving air systems, hydronic heat, and cooling packages. Two identical year/mileage Unicoach rigs can differ drastically due to storage conditions, maintenance discipline, and modifications by prior owners. That’s why independent inspections and document-backed histories matter far more than brochure specifications or a quick driveway demo.

Thinking about your own experience with this model family? Share what surprised you in ownership—costs, parts availability, or the quality of dealer support.

Second Reminder: Get an Independent Inspection Before You Sign

The single most repeated advice across forums, owner videos, and consumer advocates is to obtain a third-party inspection before closing. Without it, you risk inheriting an expensive project with limited recourse. Reputable inspectors are busy; book early and confirm they work on diesel pushers. Start with RV Inspectors near me and request a sample report from previous Class A assessments.

Final Summary and Verdict

Foretravel Motorcoach Unicoach models occupy a special niche: premium construction from an admired builder, now aging into a high-stakes buyer’s market. Reported issues concentrate around air suspension leaks and brake system maintenance, hydronic heat failures, engine cooling system repairs, fogged windows, slide seal management (on slide-equipped units), and electrical modernization needs. Add to that long service queues and parts-sourcing challenges on legacy models, and the ownership experience can be rewarding—but unforgiving to the unprepared.

Prospective buyers should:

• Rely on an independent inspection and a strong contingency contract.
• Validate recalls and VIN-specific service history through NHTSA.
• Interrogate ownership records for cooling system, hydronic heat, and air system care.
• Budget generously for near-term refreshes and potential downtime.
• Leverage owner communities and watchdog content (try searching the Liz Amazing channel) for problem-pattern awareness.

Given the concentration of aging-related failures, high repair costs, and documented service delays for many Foretravel Motorcoach Unicoach units, we cannot broadly recommend this model family to typical first-time buyers or travelers on tight timelines/budgets. Consider newer alternatives or other brands/models with easier parts access and documented, recent service histories—unless you have a thorough inspection, robust maintenance budget, and high tolerance for downtime.
