Just started a new business and I'm looking for info on trucks. Here's the deal I have a 2006 GMC 2500 6.0 withe a 4:11 rear. I can pull a house down but the gass is killing me. I'm not bragging the truck is a left over from an old business where I did not have to pay for gas!!!! I'm thinking of trading for something with a different rear and a smaller v-8. I tow a 17' duel axel covered trailer with all the goodies. Nothing to fancy. I will need the payload to carry a ton of fert. or a pallet of sod. I see lot's of guy's in the area with trucks that I think are overkill. Like f-350 towing a 16' trailer with 1 z-mower and some other supplies.
