It might be doable if it's the same type of TV stand as what's in my 2000 Jayco. What may be a deciding factor, though, is where the stand is mounted in your bedroom. Mine is mounted on the left (driver's) side wall. You lift it up and lock it into place. I've put my laptop on there to watch DVD movies. The base of the laptop measures 14-1/4" by 10-1/2" and the screen measures about 15-16" diagonally. As I recall, a bit of the laptop overhung on two corners because I had to turn the entire computer in order to aim the screen toward the bed. I would think the "footprint" of an LCD HDTV to be smaller, thus making it easier to angle it toward the bed. As an example, I have a Dynex 19" HDTV in our bedroom here at home and the base is approximately 10-1/2" by 5-1/2".
I know this is a little bit of an investment, but assuming that you're buying an LCD HDTV, I think installing a regular TV mount somewhere higher than the stand (but still close enough to the antenna hookup and power outlet) would be give you better results. It would secure the TV (which could be bumped off the stand) and, being higher, it would be easier to watch while lying in bed (you won't have to prop yourself up as high to watch it). Actually, in my TT, I find it a tight fit getting between the bed and the stand when it's in use.
Hope this helps.
