I know alot of people dog yakima for off road use...But I have one on my 80, and if properly mounted, and tightened down, it can handle some ABUSE. We wheeled alot this summer in off camber situations just ramming that thing into pine trees, large braches, and it faired quite well. It will hold 200-300lbs...I would not go over that, but if you have a 100, are not planning on trashing it in the forest, you can get really set up for 300 bucks. I have kayaks, bikes, a large basket, and one of those molded plastic aerodynamic cargo gizmo's and they all come on and off easily, making it a snap to re-configure for different excursions. The caro holder is great for winter, and with 2 kids and a dog, space is always at a premium. I have hauled ass for days in a row down chattery dirt roads, nothing comes loose. Now I'd like something more bad ass for in the future...It would suck to break your rack on an outing..but for the money and functionality they are great. And I do like Yakima over Thule...but that's just an opinion.
You can do 3 rain gutter mounts per side with 3 cross bars, bolt anything to that crap and it's pretty stout.
