I agree with you, hosejockey. I've had a lot of experience towing(I don't have it anymore, but used to have a class a CDL with tanker and doubles endorsements, and drove 70-100klb combos while landscaping)
I previously had a 3/4 myself, and used it heavy for construction work on my house, but, I also didn't have a trailer then. With a trailer, anything that would be THAT heavy, I prefer the lower deck height of the trailer, anyway.
for example, I loaded 44 10ft long wolmazined 4x4s in there. that would put a hurt on 1/2 ton, but a 1/2 ton with a trailer would be fine.
My hopeful long term wheeler will be a 4 cyl flattie, so nothing heavy at all.
