Condition is the important factor when buying a used RV. And make sure the floor plan works for you.
You are wise to ask questions BEFORE you you spend your money.
We have a 96 Southwind with AutoPark. It has not been a problem. Autopark would not be my first choice but, if I liked the unit I wouldn't hesitate to purchase the Bounder.
It's no different than buying an older RV with a carburetor as opposed to something with fuel injection.
The systems are different but in the end do the same thing.
If you like the Bounder buy it and enjoy your travels.
