Welcome to the Forum. I purchased a 8281 Rockwood last fall and have a sidewinder with a Reese 16K hitch. It provides lots of clearance and I am told backs better, don't know because I have not had experience with and other. The side winder has been a bear to hook up to however. I ordered a hitch specific wedge for it and installed it yesterday. Works great. Easy hook up and unhook. This made a world of difference. If you should go with the sidewinder just ask the dealer to install the wedge designed for your hitch and not the universal wedge. It only cost 50 bucks from etrailer and was here in a couple days.
