I just replaced my Magnadyne stereo with a double-din dashboard radio with DVD player. I originally planned on using an RV-specific stereo to avoid the cabinetry work, but turned away from every one I found after reading the reviews. The reliability reports are horrible: died after 2 months, died after 6 months, etc. I was willing to spend a few hundred bucks for something good and never found it with the RV radios. Since you're selling the RV, my suggestion is to minimize the work you have to do and just find something that fits the hole in the wall. Whoever buys your unit isn't going to give you extra credit for spending hours and hours doing something better.
