Not to hijack OP's thread, but I'm looking for a strong 2 bike rack. I had a chance to look at pretty much everything at Sea Otter last weekend ... no 1Up presence in the vendor area, but lots in the parking lot and I know a couple of happy owners. But there was a new version of the Kuat Sherpa which was appealing; it has a lower profile to clear a folded down pickup tailgate when empty of bikes and not tipped down. I don't know if that is needed, but if I ever get a high-clearance bumper it may be useful. Plus, I like the more finished design of the Kuat's. Anyway, my question regarding 1Up for two bikes max: is it worth paying a bit more for the Super Duty version? Bikes are not likely to be more than 30 pounds each, but I'd like to be able to do extended washboard and offroad with no worries. Thanks.
