I am like RVNevada, I haul a 4 seat RZR that has a dry weight of 1,400 lbs, and I know I am close to that 1,800 lbs full. You should not have an issue. I end up with all four tires on the ramp at once, but the wheelbase has them at the top and bottom of the ramp when they are all on there. You should not have any issues.
The real trick is if you set it up to unload going down the road like the old Knight Rider TV show!
