I’ve asked 5 people and got 4 different answers. Pull forward, back up, or just right?
That's exactly what I do and haven't had any issues towing my xp4 with my tundra. Tows like a dream.No way to answer your question. Whichever position give you at least 10% of your weight on the truck hitch. Anything less you are likely to have a sway issue.
My rough rule of thumb when loading anything and pulling with my pickup is to slowly pull forward enough to get the rear of the truck to drop 1-2". With that said, my hitch is rated for 2,000 lbs so it is relatively hard to overload, depending on what your hitch and truck is rated for that may be too much drop. On my other truck it has auto air leveling so I have to have a decent idea of weight distribution since it will not squat.
I could put my machine as far forward on the trailer as possible and still be within my ratings.
