Welcome to the forum and congrats on your Bounder. You're going to love it.
I can't help you with Bounder questions. I have a 96 Southwind, 454.
I've had no major problems.
Check the age of your tires, RV tires usually age out before they wear out.
And, you probably have a P 30 chassis equipped with AutoPark.
When you put it in 'Park', a set of brakes clamps around the driveshart to keep the unit from moving.
The AutoPark can be a little annoying at times. Do a Google search or search the forum. There is a lot of info available to help you maintain and/or troubleshoot the AutoPark system.
