Saw this Harley on the back of a 5er yesterday

Let's say 800# with the lift.

Just eyeballing it, the bike is probably twice the distance behind the axles as the pin is in front of the axles. That translates to around 400# off the pin weight.

In addition both weights wind up on the axles or about 1200#.

So if you trailer has 2000# of cargo capaicty, you are down to 800#.

Is that the new "fuzzy math"? :) If you were talking about a single axle trailer then you might be close, if you actually measured it and not just guesstimated. I hauled a swivel-wheel type trailer behind my Big Sky 5th wheel. I weighed everything, both before I hooked up the trailer and after. The trailer weighed about 1200 lbs., and 600 lbs. was added to the weight of the 5th wheel. IOW 600 lbs. was basically hanging off the back of the 5th wheel. It changed the pin weight by 40 lbs. Much less than the 400 lbs. you're guessing at. By an order of magnitude actually.

This is real life and not conjecture.
