Wow. First I gotta say, I can't beleive someone put a 5th wheel in their Frontier. Thats crazy. I would have thought that pretty much any 5th wheel setup would have been over kill for our trucks. Thinking that sure you could put the receiver in, but what kind of goose neck trailers would be small enough to pull. But apperently it can be done. Ha. I didn't even know they made goose neck trailers small enough to not even put us over weight, with just the trailer???
