HarveyRV had recommended Well-Nuts in this thread:

I used them to mount two LCD TV mounts to the interior of the upper shells (one in the middle of the back shell street side, and one on the front street side wall near the dinette) for a 19" LCD.
I bought one of these LCD mounts at walmart.com for the front:

And one of these for the back:

The part that attaches to the wall is the same on both mounts and is very thin. The rest of the mount slides over it - so you can easily remove the LCD with the rest of the mount attached to it.
I did take a hacksaw to the little hook that acts as cable management at the bottom of the mounting bracket because I did not want to chance anything cathing anywhere when opening or folding down.
I've also built a felt lined box in the storage area out of some scrap plywood to hold the LCD (with the rest of the mount still attached) when in transit - will try to take some pictures next time I have the TM out.
Just got back from a 10-day, 1700 mile trip and the mounts and well-nuts did great
