Well, the weight split on the Xterra is probably about 60% in the front, 40% in the rear. Given the weight is probably about 4,100lb. at best, I was probably only lifting maybe 1600lb. Still over the tongue weight limit of the hitch, for sure.

OTOH, I also quickly put jackstands under the axle and those were doing some of the work, too.

If you think about the design of the tubular hitch, how it curves down to the middle, lifting the truck with it probably stands less chance of bending something anyway.

Now, crawling under the truck while it is lifted like that - no way.
