I towed the CD25 with a Jeep GC for a few hundred miles. No troubles, but then there were no tricky situations, either. With the trailer hooked up, the Jeep wheels weighed 4700 and the trailer wheels weighed 7400 if I remember correctly. It would have made me feel less nervous if the weights were the other way around.
I now have a Dodge 1-ton, Cummins HO, 4WD, auto, 4:10 gears, single rear wheels, and 13k tow package. It has the big cab and long bed. No problems. Gets 18mpg empty and 12.5mpg the last time I towed the boat for any distance. I have never weighed my CD25 loaded without the tongue hanging on the hitch, but with the steel trailer, all the extra cabin weight as compared to the newer CD25, and all the junk we seem to need, I would be surprised if it was less than 8000 pounds. It still outweighs the tow rig, but not by much.
