How old of a 1/2 ton are you towing with now? The reason I ask is that my 05 chevy with a 5.3 struggles with my tractor on a 20' bumper pull. I get it done, but I take my time getting up to speed and give myself plenty of room to stop. It's probably pushing 7000# or so. The 24 1500 my wife had with a 5.3, pulled it with no trouble. I was thinking of going 3/4 ton when it's my turn, but I've probably changed my mind on that. Her truck also got 20-23 unloaded. The 3/4 ton Chevy with a 6.6 gas motor we have at work, gets around 14 unloaded.
