Interesting. My 1/2-ton Suburban with a GMC 270 runs great empty, but gets doggy with an empty 18' trailer behind it. Loaded its really slow. I figured it was my 3.08 gears but maybe not...

I usually pull the trailer with a 454 and 4.11 gears. Easier on everything but the fuel budget.


1955 1st GMC Suburban | 1954 GMC 250 trailer puller project | 1954 GMC 250 Hydra-Matic | 1954 Chevy 3100 . 1947 Chevy COE | and more...
It's true. I really don't do anything but browse the Internet looking for trouble...
