What owners report

The vehicle was taken to an independent mechanic, where it was diagnosed and determined that the OE system had two hoses connecting to the distribution box and A/C, but had no way for air to reach the far right and left vents. The vehicle was repaired by modifying the system to direct the air to all the vents.
The RV was taken to the dealer where the RV was diagnosed, and it was determined that the front chassis had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 48,900.
The radio (and camera system) had been acting strangely and my cigarette outlets stopped working while I was driving. I stopped for the night and had parked and connected the rv to the campground power.
Axel hangers on the passenger side of motor home were loose, found that this is a problem with the motor-homes very unsafe when towing a car or trailer. On highway traveling had to stop and get it torqued to continue.
