The F53 chassis is designed for dozens of uses. Motorhomes only being one. It is not an "unsafe" product. It simply requires adjustment. Unfortunately this is not done at the factory. Many need alignments, most the the psi is not set accurately, the weights are not always accurate and the sway bars can be adjusted (front and rear) . While I agree that all of this should be done by the manufacturer or at least the dealer, you can do all of the above for a nominal price if not free for most. It does help if you tell us what kind of MH it is. Get the alignment checked, weigh it and adjust psi and loading accordingly and since you already have a front bar, adjust the rear sway bars to the tighter position. It has to be set up or it will drive like a pig. BTW guys, "get a DP" is not always the answer. Stick to the topic.
