I know it's too late for you, but I purposefully didn't order an optional radio with mine. I found that putting an aftermarket stereo (cd or whatever) is pretty straightforward, and more satisfying. I have already replaced the front speakers, with some difficulty and will soon do the same in the back. I am really sorry you are struggling so much wiht your unit. I have several problems that have been identified and I will get fixed eventually. I anticipate from your comments that you are pretty disgusted with the small (and big)problems that keep hounding you. Were you told that the vehicle was going to be trouble free when you got it? That sounds sort of insipid, but the dealer here cautioned me that I would have a list of things to get fixed after driving the unit a couple of months. I do get frustrated with some of the discrepancies, and fix them myself (as you attempted with the window).
Can you say how you feel driving the motorhome? How does it handle, and what about the power? Did you test drive a smaller unit for comparison? I guess I am wondering how you like the idea of that size vehicle?
