I just did this in my MH I recently purchased. The front TV was in the center of the coach over the dash it was a 27" old school TV. I replaced it with a 32" LED flat screen and it fit perfect inside the cabinet. I made my own mount by using 2 shelf brackets attached to 2 of the holes they provide for a mount. I purchased 2 M4 machine screws to attach the shelf bracket to the TV I then screwed the shelf brackets to a scrap piece of 2" x 6" I had in the scrap pile and screwed that to the floor of the cabinet. The TV had legs so I screwed a piece of web strap about 3" long over the front feet into the floor of the cabinet on each leg. It is rock solid plus the new TV doesn't weight very much.
I wanted to go bigger on the front TV but a 40" TV would have not fit inside the cabinet and it would have over hung on each end interfering with the cabinet doors on each side of it not allowing them to fully open.
I replaced the one in the bedroom it was a 20" old school TV and I changed it to a 24" LED flat screen. This one I just used the web straps across the feet at all 4 corners and put a new blue ray player under it. This snugged the TV down on top of the player and it is all very solid. I will take some pictures when I get a chance.
I also replaced the old VHS with a blue ray player in the front. On our first real camping trip the Grand kids stayed the night in our coach and right away I saw the need to be able to watch different movies on each TV. This way the kids can watch their movie in the front and we can watch something more age appropriate on the one in the bedroom.
My total cost for both TV's and 2 blue ray players was under $500. The only downside is the front blue ray player won't use the built in surround sound but I left the original DVD player in place so if the movie is a standard DVD the surround sound will still work. The front speakers will still work with the blue ray but not the rear speakers I am not sure if I can fix that or not.
Before pictures sorry I did not take these I saved them from the add that I bought the MH from the only picture I could find of the rear TV was an edge of it looking towards the bedroom.
