Well I think it's fair to say I'll most likely transition from a Class III receiver to a completely unrated, untested, you'll die if you even use it, integrated receiver hitch- like you have.
"they" say that ideal tongue weight is 9-15% the total trailer weight. I think I will be in the 2200-2800 pound range depending on load and quantity of bikes. So while attractive, I think 100 pounds is going to be on the light side..
