Re: lifeisgr8
I just put a TV in mine and used a stud finder to find one good stud. Then we purchased drywall plastic screw anchors and first of all installed the TV bracket. I managed to get 2 of the screws into the stud and one screw into an anchor. We used a TV bracket that fits with our 22" TV and the bracket will come right out from the wall so we can rotate the TV around. For us, this was the ideal size of TV for function, weight and space.
One item we had to do was get a BELL TV technician into our trailer and move cable wires around in the cable booster box. There was no signal at all between the outside cable attachment and the inside "satellite" labelled cable attachment. So the cable guy fixed us all up for nothing! Now we can operate our portable Anser satellite perfectly with our satellite system.
Consider the weight of your TV hanging in the wall. Carefully think out securing of your TV bracket to hold the weight of your TV. Also consider the weight of your TV mixed into your GVWR of your trailer.
Good luck!
