I was thinking the same thing but it's another $2,700 to jump up to that one. Granted you get a few other nice options like shocks, bigger tires, a front storage rack and box, as well as a stronger frame.
At this rate we are approaching almost $10,000 for this trailer with options like awnings, a road shower, and the electrical package and I don't think we want to exceed that. Plus, my Jeep isn't that big and to tow a trailer on off-road terrain like that I would want/have to do some more upgrades which would require more cash... And the trailer would have bigger tires than my Jeep!
