I can tow a MC and snowmobile trailer with no problem.
Some boat trailers seem fine yet others have problems.
I think it depends on the distance from the coupler and the height of the boat winch. You should be able to test it using a yardstick or something similar. Measure the height of the lift gate from the ground and the length of the liftgate and test it from about a foot in front of your coupler. I can tow a MC and snowmobile trailer with no problem.
