I'm buy this primarily to use with a rooftop tent, and I ordered the Front Runner tent mount kit with the rack. It'd also be great for carrying some fuel for the bike (probably in the form of Rotopax), depending how much space is left over.
I had an African Outback tent on my LR3 on stock crossbars, and while the tent was great, I was limited on how the tent could be mounted. A good rack should give me more flexibility.
I've been keeping an eye out on the classifieds section, but I'll probably go with a new Tepui or CVT unless something compelling shows up.
