With a fifth wheel, it's not so much the length of the trailer as the gross weight and how much weight the trailer puts on the pin. We pulled a 14,000 lb., 36' fifth wheel with a CC 6'6" bed Sierra with the Duramax/Allison and it pulled and handled very well. Because it was a 3/4-ton truck we were at the upper limits for our payload (the truck had 3,100 lbs. payload per the scales fully loaded). We are full-timers, so when the chance came along to move to a very good DRW truck, we jumped on it. Having the extra payload with the 1-ton DRW also made it possible for us to upgrade to a heavier fifth wheel this year, too.
