Sorry for late reply, van was at the shop.
We initially got this setup as a loophole to not need a wrecker at a race event we used to put on yearly. The idea was that the van weighs at least 3x what any of the typical racecars at the event, so theoretically we could either get the car back to the surface or worst case secure car until driver was extracted and a real wrecker was dispatched.
We never had to use it for why we purchased it but have used it to free a few friends but itís been used for firewood gathering more than everything else combined, so I canít say that this setup could rescue myself from a jam. The one time we tried it was basically to pull us up an icy incline where I couldnít get a run. It worked well but the only resistance was gravity. Not 4-35x12.50 tires sunk to the axle in thick gooey mud.
Sorry for the excessive rust. Had van in an area over thanksgiving where they use the mag cloride as snow melt and I never had a chance to spray it off. Rust happens quick with that crap. If you need more pix or info, just ask. Happy to help if I can
