I hung this TV ceiling mount in my RV underneath one of the overhead cabinets and it took me less than 10 minutes to bolt it down. We have since gone over bumpy roads in the RV and the mount has stayed in place. You can lock the TV in the upward position before placing the RV in motion (a big plus). Very nice mount for the price.
I bought to install in a RV Motorhome. It was somewhat challenging to install and mount. Not because of it's design, but, rather because of where I wanted to install. Actually went to a larger TV size than noted in advertisement. I went with a 40 inch flat screen up over the passenger side dash and under the ceiling cabinet panel. Looks great, fits great, works great. The 40 inch was not a problem, just watch the weight and mount strength. Just finished a 1000 mile plus round trip. Mostly good roads, some not so good (rough). The mount worked perfectly, no problems with any feature. Would recommend to anyone, just mount securely.
