I installed the mount myself in our M32 and had my husband assist in attaching the tv as I didn't want to drop it.
With the advice of others, I went with a Moryde self locking, full movement mount. Love it! Much sturdier then the cheaper mount I used in our prior camper. The movement allows you to sit in the couch and comfortably watch tv.
I called Heartland and spoke with them regarding max size, weight, and install. There is plenty if support in the center of tv area. I used the hardware that came with the Moryde mount. We have traveled thousands of miles with no problems and have been overall very satisfied.
A 40" smart TV is what I ended up with. The following full motion mount along with the VESA adapter plate as the TV I choose was 200x200 pattern.
