Re: towing capibility of trailblazer 5.3 v8
6200 pounds is with no accessories added to the vehicle, no cargo, no passengers. Just a 150 pound driver and a bit of gas. So, as long as the weight in the truck is less than 500 pounds, you may be able to tow 5700 pounds. But if it is empty, why bother towing it; an empty RV is not of much use.
You sure you will never have more than 400 pounds of food, water, sewage, clothing, tools, hook up supplies, utensils, manuals, tapes/dvds, games and gadgets?
