I just installed two 22" JVC LED/DVD combos in my 2010 26BH. I love them, but I have not seen how they do in transit. I have them mounted very securely though.
I bought this mount because it is two screws that mount in a straight line. This makes it so I can hit the stud where as other mounts may have four screws and two would hit but two probably wouldn't... This unit also has 2" screws that come with it which are a #12 size. http://www.amazon.com/VideoSecu-Arti...5942932&sr=8-3
The JVCs I bought were at Sams Club for $230 each and they are nice because they have DVD player on board so no need to mount a shelf or anything. http://www.amazon.com/JVC-LT-22EM21-...5943263&sr=1-1
I did contact Jayco for the wall plans and they provided them, but the studs were not where the plans called for. I measured about 20 times and drilled a couple holes and nada.
In the bedroom area I was able to tell quite easily where the studs were and actually calculated thing just right so I hit one of the studs the kitchen cabinet was mounted to on the other side of the wall.
The kitchen one next to the radio unit was the one I had a tough time with. Plans weren't what Jayco had. I was able to find a stud just above the thermostat. I bought some 1" #12 screws at Lowes for $1.05 and they worked perfectly since the wall is 1" and the bracket is 3/8" I didn't go through the wall.
If you would like I will go take some photos for you a little later. Right now it is snowing here in SLC and it is still dark.
