I bought this mount and installed it before our trip and worked great
VideoSecu Low Profile Ultra Slim 1" profile TV Wall Mount for most 27"-47" LCD LED Plasma TV, Some up to 55" Flat Panel Screen Display with VESA 100x100 to 400x400 1RX https://www.amazon.com/dp/B002TZ4CRG..._uXgnvb171NVE7
I used all the hardware out of this kit. I predrilled the holes to just over 3/4 inch deep because I didn't want to drill all the way thru the wall. I then cut down the anchor bolts to 3/4 inch. I like this mount because it has auto locking clips with the straps that hang down making it easy to get off if you want to take it with you. I took it over a 100 miles with no problems.
