Got'er all mounted up today. I decided against the tripod idea because $150+ was just too steep and seemed ridiculous. I went off of Billman's idea and it worked great.
I'll unhook it from the wall mount and set it on the bed when driving down the road, but it is super solid. The load is distributed through 3 studs and it is very sturdy. It doesn't even flex. I paired our tablet and smart phones to it to watch pre-downloaded movies and tv shows wireless from the Dish Anywhere & Showbox Apps. If I get a good enough signal at Dumont, we'll even be able to watch live TV without the use of satellite. The whole goal was to avoid several hundred dollars worth of satellite equipment and monthly billing. Couldn't be happier with the way it worked out.
This 42" LCD is going to be nice for movies out there! I mounted it lower than most do because we don't like having to look up so high. It worked out great. There's not a bad seat from anywhere on the couch or dinette.
I countersunk the bolts from the back so it fit flush against the wall.
ready for the tv mount
Mounted over 3 studs in the wall with 10 good sized wood screws which seated very tightly.
walla!
