It makes little sense to me to have the load on a trailer behind the axle. It seems to me that the trailer bed should be centered over the axle or the center of the bed slightly in front of the axle. Having a heavy load in the bed that is behind the axle will most likely cause the trailer to sway.
Maybe I am missing something about why this type of trailer configuration would be appropriate.
Thought about doing this... But the JT bed is too small to be worthwhile & the axle placement for a trailer would be dumb. Need to move the wheel wells back.. Realistically good fab skills to extend the front a good little bit would work, But it would be way more work then doing something from scratch that would still hold the jeep spirit.
