It isnt the weight that is the issue, in my opinion... The wind, was the great azz kicker.... these things make plenty of power, and the springs are strong enough. I had fat tires on 20 x 10 rims, and 4.10 gears. The 13 foot 6 inch sail swinging behind a SRW truck is the unfixable issue... Like ForceFed said, we both learned the hard way...
If you arent forced to be anywhere, and can squat for an extra day or so to avoid bad weather, you should be fine. If you dont have that kind of lee way, ehhhhh.... I wouldnt....
