The excavator is 1.8+ an aluminium trailer, I think it would be right on the limit. I agree a diesel would tow better but it's not going to be very often, once every 2 months max. I'm just wondering how it would go, I'm sure it would be a to put up with it, hopefully. I would get a diesel but I can't stand them. Too slow and sounds like your driving a tractor around, no fun in that haha
