[66x3]

I tow a small camper trailer, a 16 ft car /equipment trailer or sometimes carry a Approx. 2000# slide in camper with my C 20 and seem to do fine with my drums. They are pretty big brakes and truck/tractors have used drums for decades although just recently started using discs. Maybe Studeclunker should weigh in on this as he seems to tow some pretty big vintage trailers but I don't know if he has switched to discs or still has drums. I for sure switched over to a dual master cylinder.
