What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
[xxx]--I was towing a vehicle behind a tiffin motor home. A tow bar attaches the towed vehicle to the motor home tow hitch. The tow bar began to sag while driving on a highway. The tow hitch is welded to a tiffin installed frame, that is welded to the vehicle chassis.
Shortly after engine start and during or shortly after warm-up, when accelerating from a stop, the engine loses all power. If you hold the accelerator pedal in one position, it will remain at idle. If you pump the accelerator pedal or push to the floor, it will catch up and accelerate.
The consumer stated the propane furnace produced a rattling noise and it gradually became louder, as if something were loose in the furnace. There was also a unique odor, as if something were burning. Every time the suburban propane furnace was in use, the noise became louder, and the odor became worse.
Extreme amount of sway. Twisty roads have to be under posted speed limit. Freeway travel is affected by wind, semi's and other high profile vehicles. Many times I have been forced off of the road on to the shoulder of the road. Complained to tiffin motors and was told to get a better set of shock absorbers.
