Ok, got it all installed and figured I would post back with my observations since there wasn't much real user feedback out there on this rack. I've got a link at the end of this post to photobucket with some pics, hopefully it works I haven't used photo hosting before. First off I had a local welder fabricate and weld on a hitch to the main trailer frame rails so it's not attached to the bumper in any way for support. I was impressed with the overall quality of the RvRaxx. It seemed to have had a lot of thought put into it's design to maximize strength. The materials used were of good quality and more than adaquate in strength. The finish was also very good in quality. While it did come in pieces and required assembly it wasn't difficult to figure out and put together. I wasn't entirely pleased with the assembly hardware. A couple of the bolts were a bit too short for my liking as well. I ended up buying all new grade 8 bolts locally for the assembly. The way it's designed to attach to the hitch tube prevents you from using a locking hitch pin but it does eliminate virtually all side to side play in the hitch tube to make it more stable.It uses a threaded bolt and a nut inside the RvRaxx tube to tighten and then another lock nut on the outside of the hitch tube for attachment. The nut inside the tube had sticky tape to hold it in place, I didn't care for that and ended up tack welding the nut into place. While this attachment eliminated any side to side play in the hitch tube there was still up and down play. I installed one of those anti-rattle hitch clips which now eliminated any play in the hitch tube at all. RvRaxx has an optional support that is supposed to go from the upper rack crossbar to the trailer roof or rear wall to help stop any upper rack bouncing. I didn't really want anything attached to the roof or rear wall. I fabricated and attached a 1 inch square tube from the upper crossbar to the rear bumper which I feel confident will accomplish the same thing. The other thing that concerned me a bit was the kayaks just starting to mask my rear tail lights. I didn't want to take any chances of not being seen when I hit the brakes or turn so I added a set of led tail lights to the rack and tied them into the trailer circuit with a disconnect plug at the bumper. The kayaks seemed to flex more in the nose and flatten out a bit when I put them in the rack nose down. They seemed to fit better without ony distortion when I put them in tail down. The way I have the rack adjusted I have 17" ground clearance with the kayaks, the hitch would hit before the kayaks. And they stick up 15" above the aft roofline( the roof slopes down to the back), my ac unit is still the high point for my overall height.
