Forest River-Vengeance Super RV Exposed: Leaks, Axle Alignment Failures & Slow Warranty Service

(Serious Concern)

Across Forest River toy haulers, owners frequently document leaks at roof seams, slide headers, and cap joins shortly after delivery. The Vengeance-branded units are no exception in online reports. Typical patterns include water trails at slide corners, bubbling ceiling panels, and delamination along exterior walls—classic signs the substrate has absorbed moisture. On a toy hauler, these leaks sometimes manifest first in the garage or bedroom slide areas. Verify patterns and photos through these searches: Google: Vengeance Super water damage and YouTube: Vengeance Super leaks. Compare with owner narratives on RVInsider and Good Sam Community.

(Moderate Concern)

Owners of Vengeance “Super” style toy haulers report ramp doors that don’t compress evenly at the gasket, allowing rainwater and dust to enter, especially when parked slightly nose-low. Saturated garage flooring, wet tie-down tracks, and mildew smells are common indicators. Before delivery, hose test the ramp perimeter and check for water intrusion along the threshold and sidewalls. See discussions and troubleshooting tips via r/rvs discussions and this targeted search: Google: ramp door leak Vengeance Super.

(Moderate Concern)

Units that rely on butyl tape plus sealant around windows and marker lights can leak if not bedded correctly at the factory. Owners document puddling on sills, streaking under marker lights, and stained interior wall panels. These issues often show up after the first heavy rain or a pressure wash. Inspect carefully and review peer reports via Google: Vengeance Super window leaks and YouTube: Vengeance Super water leaks.

(Serious Concern)

Multiple owners across Forest River toy haulers cite premature tire wear, scalloping, and heat buildup traced to axle misalignment and spring hanger issues. On heavy, long toy haulers, alignment matters: with toys in the garage and tanks loaded, misalignment compounds, leading to blowouts and unsafe handling. Before purchase, request a four-wheel alignment report and examine tire wear patterns on the lot. Review threads and photos here: r/GoRVing results, Google: Vengeance Super axle problems, and RVInsider complaint narratives.

(Moderate Concern)

Inconsistent brake response and wiring splices that aren’t well secured appear in owner reports for similar Vengeance units. Symptoms include intermittent brake controller errors and one side grabbing more than the other, sometimes traced to poor grounds or chafed wiring near the axles. Ask the dealer for a complete brake inspection and drum measurement. Evidence threads: Google: Vengeance Super brake problems, YouTube: brake issues on Vengeance Super.

(Moderate Concern)

Owners routinely post photos of chaotic wiring behind panels—loose bundles, unlabeled connections, or improperly crimped terminals. That can mean random 12V failures, dimming lights under load, or GFCI trips when on shore power. Check panel labeling, load-test batteries, and ensure the converter maintains proper charge voltages. Verify with: r/RVLiving search and Google: Vengeance Super electrical problems.

(Moderate Concern)

Because the “Super” is a toy hauler, owners expect an onboard genset and fuel station. Reports note fumes in garages, fuel leaks at fittings, and fuel pump failures. Thoroughly run the generator under load (A/C + microwave), test the fuel station nozzles, and inspect all lines for drips or odors. Cross-check with Google: Vengeance Super fuel station problems and discussions within RVUSA Forum.

(Moderate Concern)

Owners complain of uneven cooling, poor duct sealing, and insufficient A/C capacity for larger Vengeance floorplans—especially with sun exposure and heat radiating from garage doors. A poorly sealed plenum can cause cold air loss into the ceiling cavity. During PDI, use an IR thermometer at vents and check delta-T. See owner trials via YouTube: Vengeance Super A/C problems and Google: HVAC issues.

(Moderate Concern)

Short-cycling furnaces, soot around exhausts, and water heaters that only run reliably on one energy source (LP or electric) appear across owner complaints. These are often supplier-component issues but compounded by rushed installation. Demand functional demos on both energy modes and a carbon monoxide test. Validate with: Google: Vengeance Super water heater problems.

(Moderate Concern)

Owners commonly report loose PEX crimp rings, drips at elbows, and under-sink leaks after travel. A few hours of full-pressure testing in the dealer lot can expose these faults. See: Google: plumbing problems and owner threads in RVForums.com.

(Moderate Concern)

False-full tank readings, sewage odors entering the coach, and burping vents show up in many toy hauler threads. Tank sensors are notorious; more concerning is venting that is kinked or misrouted during assembly. A smoke test during inspection helps locate leaks. Research examples through r/rvs tank problem threads and Google: black tank odor Vengeance Super.

(Moderate Concern)

Reports of staples popping through trim, misaligned cabinet doors, and weak catches appear frequently in Vengeance-class rigs. This undermines the “adventure-ready” marketing message. Inspect every hinge and latch, and drive the unit a few miles before finalizing to expose rattles. See aggregated complaints: Google: interior quality issues and video examples from YouTube: fit and finish.

(Moderate Concern)

Toy hauler garages must convert smoothly into living space. Owners describe jammed or out-of-level power bunks and sofas, squeaks, and hardware loosening over time. Confirm the lift system cycles under load and inspect mounting points into the walls. Compare experiences via Good Sam Community: garage bed issues.

(Serious Concern)

Owner accounts repeatedly describe weeks to months waiting for approval and parts for even simple repairs. Dealers often prioritize customers who purchased from them and may refuse or delay work for out-of-state buyers. Meanwhile, your camping season evaporates. Survey the patterns on the BBB, Google: warranty complaints, and threads across Reddit warranty problem searches. It’s one of the strongest arguments for hiring an independent inspector and documenting a punch list before you pay. If you’ve been stuck in a service queue, how long did your repair take, and what broke?

(Moderate Concern)

A recurring theme in complaints is warranty denial framed as owner misuse or wear and tear—especially on exterior seals, ramp doors, and slide adjustments. Keep a dated inspection log, photographs of seals pre-delivery, and written dealer notes to fight unfair denials. Research patterns via Google: warranty denial and compare stories on RVInsider.

(Serious Concern)

A common shock to first-time toy hauler buyers is how little cargo capacity remains once options are added and tanks are partially filled. With the Vengeance “Super,” owners report being closer to GVWR than expected, limiting the safe weight of toys and gear. Overloading risks axle, tire, and frame failures. Demand a certified empty weight ticket for your exact unit and run your own CAT scale tickets with your tow vehicle. See discussions: Google: weight issues and forum debates at RVForum.net.

(Serious Concern)

Forest River units—including toy haulers—have seen recalls spanning LP regulators, suspension components, and awning hardware in recent years. Specific campaigns vary by year and floorplan, so run your VIN on NHTSA and monitor regularly: NHTSA recall search for Vengeance Super. Owners sometimes report delays in parts availability and poor recall communication. Ask your dealer for a printout of open campaigns and completion proof.

(Moderate Concern)

RV warranties are governed by the Magnuson-Moss Warranty Act, which requires clear terms and prohibits deceptive practices. However, RV lemon law coverage varies by state; in many states, motorhomes may have better coverage than towables. If warranty work drags on for unreasonable timeframes or defects remain unrepaired after multiple attempts, you may have claims under state consumer protection statutes (UDAP laws), breach of warranty, or implied warranty of merchantability. Document everything: dates, communications, repair orders, and out-of-pocket costs.

Regulatory bodies to engage if you encounter serious safety or warranty violations include:

• NHTSA: File a complaint for safety-related defects: brake failures, axle/suspension defects, LP system leaks.
• FTC: Report deceptive advertising or warranty practices.
• State Attorney General/Consumer Protection Office: Pursue mediation or investigate unfair business practices.
• BBB: While not a government agency, complaints create a public record and sometimes prompt faster resolution: BBB: Forest River Vengeance Super.

If you’ve escalated legally and achieved resolution (or not), what did the manufacturer or dealer do after you filed?

(Serious Concern)

Water intrusion threatens structural integrity, causes mold risk, and can devalue the unit by thousands if delamination sets in. Leaks at slide corners or ramp doors are not trivial—left unresolved, they create expensive repairs that sometimes exceed extended warranty caps.

Chassis, axle, and brake issues directly impact safety. Misaligned axles combined with heavy garage cargo can precipitate tire blowouts and control loss. Brake inconsistencies raise stopping distances. These are not cosmetic problems; they put families at risk.

Electrical defects can lead to tripping breakers, dead batteries while boondocking, and in rare cases, fire hazards if wiring is chafed or poorly terminated. Generator and fuel station failures compromise the core promise of off-grid capability—a main reason for buying a toy hauler in the first place.

Warranty delays multiply the damage: by the time parts arrive, leaks have worsened, and a short camping season slips away. Financially, owners face loan payments, storage fees, and lost camping reservations. For full-timers, extended shop stays can become housing crises.

To judge overall risk for your situation, weigh the probability of these failure modes against your use case and capacity to self-repair. If you aren’t handy and rely on dealer service windows, risk exposure is higher. If you have tools, time, and experience sealing seams and aligning axles, you’ll mitigate better—but still confirm recall and warranty support timelines where you plan to camp.
