Gentleman, I have a question, I'm about to attempt to haul a very heavy excavator roughly 21k on a 20k rated gooseneck that weighs around 5200 lbs. Behind my 12 3500 srw. Does anyone with any heavy haul experience have any input. Coming from Johnson City TN to Jacksonville FL. I have a CDL and know better but I need to move this machine. I've made this run several times with my 03 2500. But haven't had the 12 long enough to have a good feel for it. If that makes sense. Would you guys attempt it? Thanks in advance. Oh and I have thick skin so don't worry about the feelings LOL.
