Yep its a quad. Pulls like a mule. I was scared to death the first time I hooked up. The rig seemed pretty large, compared with what I was used to. But its getting better, as I get used to the size.
And the Cummins is pretty amazing, we are working it pretty hard but it'll maintain about 50 on a 6% grade loaded for camping, which I am guessing a bit, but about 21-22k. Out on the freeway cruising, sometimes you really forget its back there, its that stable.
