Not a problem,
2500 HD would you believe this truck 3/4 ton with a 5.7 4-10 rears can pull a 8240 lb 5th wheel with out any trouble?
I WOULD!... my friend has a newer 4x4 2500HD Diesel. It is a very tricked out truck. Everything any truck guy could ever want he has on this truck. He told me of a story one time where he was riding down the road (it had been raining and we live in Georgia) and he saw a school bus full of kids stuck in the mud... the story writes itself.
Hmmm...a 3/4 ton 350 with 4:10 gears? you must be on a first-name basis with every gas station owner for miles.
