I was just speaking to my dealer and he said that the add a room has to be clipped to the side of the trailer, where there is permanent fastened hardware attached. I really don’t want to make any additional holes in the trailer. As such, how well does the add a room work if you don’t use the mounting hardware to fasten it to the side of the trailer? Presumably there will be a bit of a gap but how bad is it? Is it still worth doing?
