I'm about to pull the trigger on a permanent mount roof bike rack for my PUP. I've read nearly every thread on this topic, this forum and others, but I would like to hear from others on your experience with longevity of these roof racks, especially those of you who leave the highway for those bumpy forest service and BLM roads like me, which I haven't found covered already. I want to protect my bikes, which are fairly expensive full suspension setups, while also looking out for my PUP's roof. I'm assuming that the bikes bouncing on the cross bars could create more stress where the rack attaches to the roof on the bumpier roads that I frequent versus the typical blacktop user. I'd also love to hear what brands everyone has used. It looks like Forest River is installing the ProRac brand permanent roof mount option on their Sports Enthusiast series, while my dealer (Roberts Sales) has used SportRack (now owned by Thule), and others prefer the Swagman Roamer. The SportRack supports 200 lbs while the other two only 150 lbs. 150 isn't quite enough for 4 bikes @ 34 lbs each and 4 nice holders like the Thule Sidearm. Yet I don't understand why the SportRack claims higher weight support when they all look roughly the same. Finally, the SportRack attaches at the roof sidewall whereas the others screw into to the 1.5" pine frame inside the sidewall. Finally, I might want to put a kayak and/or canoe on top. Seems like 36" is the cross bar spread recommended by major manufacturers like Thule and Yakima, but I'd love to hear everyone's experience carrying these toys on top of a roof rack on your PUP. Decisions, decisions... Thanks in advance! ...and no I don't want to do a hitch mounted or tow vehicle roof rack option. Trying to decrease weight on the TV, and even the fork-mount version of the ProRac that installs on the PUP's tongue doesn't give me enough reduction.
