Hey guys I am looking at picking up an enclosed car hauler for my Mach 1. I found a great deal on a 8.5'x26' trailer. I am guessing that it will weigh around 3,000-3,500 lbs empty. Then it will house my Mach 1, a bunch of accessories, tools, and God knows what else will end up in there. I am guessing that depending on the circumstances that it will weight around 9,000-11,000 lbs loaded. With the 01 in my sig, would I need WD? I think not because of my air bag set up, but at the same time that is a lot of weight for a pull behind trailer. Anyway let me know what you guys think, thanks a lot.
