GM 2500 and TH owners

I have 2500 6.0 gas, 4:10 rear, 6spd trans. I don't tow a 5th wheel but a Livin lite VRV. Loaded its around 7500 pounds. Travel all over the country with it. Do I wish it was a diesel? You bet I do, but it does a decent job for what it is. For what you want to do and the short hauls that your planning it should be just fine. That 6.0 is a gas hound with the best MPG I ever got,unloaded,not towing 15mpg. Bullet proof motor though!
