Thanks for the link. Unfortunately, the TL guides only go back to 99, and my truck is 96. If I go with the 99 guide, a similar truck's capacity (although they don't list a 4.10 for 99?) would be 13,100. The 3580's dry weight is 11,930, plus whatever options. We travel with dry tanks, except for a little fresh water, so it'd be very close indeed. Hauling a back-end full of firewood would be out of the question tho! Jon's right tho, I need to look at CVWR too.
I'm not comfortable being so close to the limit, so it looks like we'll wait til we can afford that 350 I've been looking at! We really love that BH 3580, especially compared to the Wildcat we have now; like night and day.
Thanks again.
