Where can I find explanations for all the different weight limits and capacities for trucks and trailers? I've been trying to educate myself by reading posts on this website & others, but it's hard to keep all the information straight from all the various message threads, and even then there are so often contradictions from one person's explanation to another's that I don't know what or who to believe/trust. The reason I'm trying to learn about all this is so that I can purchase a properly equiped truck and GN trailer to haul an ASV RC-100 with a Fecon Bull Hog attachment, both of which combined will weigh over 12,000 lbs. I figure I'll need several thousand more pounds capacity beyond that for such things as fuel, tools, transport chains, and additional skidsteer attachments. So is there a reliable message thread on this site or even a different website that will have trustworthy explanations and definitons for all this?
