FYI on H2 towing abilities. They are not the best. The 35" tires kill them. Besided skiing I like to snowmobile. Heading to Canada on a trip and one of the vehicles was a H2. He was pulling the same trailer as me 20' enclosed with 4 snowmobiles. He got real bad gas mileage and had a hard time pulling the weight. I guess the trailer to be 4500-5000 pounds. I was pulling with GMC 2500HD Crewcab we both have the same engine and the same axle ratio with 265 tires. I had zero problems did not even notice it back there.
All depends on what you towing and how often
