I put a 32 inch on my 270. I believe I read somewhere that the mount would not support much above that weight.
I purchased an adapter to project it out from the side of the trailer a bit, and then got an extension plug with a low profile right angle to the plug end because there was not much clearance back behind the tv.
Used it once only also, but it's nice when the weather is good.
I adapted one of the TV's from home, so the cost to adapt was low. It is there if I want it.
