Trailer extension

I got lucky when I bought my camper. It came with all the tie down stuff, brackets and a hitch extension. I gotta be honest though, even though I've got airbags and a dually, see the length of that thing makes me nervous (over 2' truss style). Even with the beefy turn buckles that attach to the frame and mid extension. The PO said he regularly towed his enclosed race car trailer with it and camper, all on a bagged 3/4ton.

I'm interested to see what others say (haven't towed with the camper on yet) as I'm debating using the extension or extending the tongue of my trailer.
