I thought I'd post in this thread that I installed the new 22" SuperSonic 12v LCD TV/DVD player and am VERY happy with it!

I bought the strap to keep it from flopping around and it did well so far.

We watched a movie in bed Friday night and it was great! Used very little power (didn't notice any significant drain on the batteries at all but only watched half the movie).
Many have complained the sound was too low and 'tinny' but we found it just fine in the camper bed frankly. Heck, I had it down around 12 on the scale from 1-100 and thought it might disturb the neighbors if it were louder.
Don't get me wrong, it is NOT loud but it's fine for inside the camper. I did notice sitting at the dinette as far from the TV as I could be that it was quiet even at 50 but again, it's a camper and I'm not expecting big stereo sound out of a TV that cost me only about $140!
We're happy we have it and I am stoked that I now have some entertainment when I'm on those long milling jobs alone in the woods :)
