All the junk in the bed plus 4 passengers that got back in it would be over payload by quite a bit.Doesn't look like it would be overloaded to me. Unsafe maybe but probably not too much tongue weight and that's a small tractor.
None of the 4 that got in were small. So I'm making assumptions, but ive yet to see a 150 with a decent payload rating.If you say so. I can't see his CCC sticker from here.
