I also have a 32' LQ 2-axle trailer when fully loaded with my 69 D200 truck I scaled it at 11,100 lbs. I used to pull it with a 2004 3500 Cummins single wheel truck but now use a 2105 2500 4x4 5.7 Hemi. It definitely pulled better with the Cummins truck, but the new one is adequate. I bought a 2-axle due to the multiple times I would be towing through Chicago tollways and didn't want to pay tolls for another axle. It would be better with another axle, but it works good enough the way it is.
