No problems with ours at all. Have two LCD/DVD models on wall brackets and they are great! Some units may require wiring the sound to the speakers built in by Airstream or remote speakers for better sound however it's not an absolute necessity. Hook em up to a MotoSat automatic dish on the roof and they're even better and it'll be just like being at home. Of course, it is a camper and unless you're forced to stay indoors because of bad weather why have TVs at all? Then again, we just have to have our techie stuff just in case.
Ya just never know when you can't do without more toys. The LCDs are getting so cheap these days you might go to Best Buy and look for a display model that is the last of stock and get a deal. Don't buy the extended warranty and you have one sweet deal for sure. We did that with one of our units.
