So a 2 door Sidekick softtop empty is ~1400kg = ~3080lbs.
Larger tires & rims, suspension lift, rock rails, skid plates, rear swing arm bumper, front winch bumper, extra battery and winch add 300-500 lbs.
Load up 2 people and mild trail gear, add another 400-600 lbs. And the little track/kick just became 4000lbs easy.
2 extra, 5 gallon gas cans, externally mounted high-lift, shovel, chain saw, and roof rack another 200-300 lbs.
Plop down a 4 door hard top, loaded with dual cases, even larger tires, massive suspension lift and even more people and gear and we've got ~5000lbs.
A little 6000lb winch just became an expensive anchor to be used on the car trailer to aid in loading up the broken track/kick
I've wheeled with people with under powered winches and have seen what a snapped cable does. Not pretty.
Be careful!
