TV mount for 42"

[boudie]

I have seen EXTERIOR mounts that hold up to a 30 inch TV but I want something with a bit more strength. I am purchasing a new TT ,forest river 320bhds freedom express , and plan on mounting it on the exterior wall.

Anyone have a mount that holds at least a 42" TV??

Obviously I am looking for the type that look slim and unobtrusive while traveling.

Thanks
