"lewi"......We just sold our 2005 Monaco Diplomat 36' SKT with a 400 ISL. This coach was an absolute rocket. It was exactly 37', bumper to bumper, weighed in loaded at 31000 pounds. I had chipped the motor and changed the engine fan. It was putting out roughly 450 HP.
We routinely towed our 5500 pound Chevy Silverado 4 door all over the country. It would pull any grade, including those through Mount Shasta and Grants Pass at 55 mph.
We also towed the Silverado, on occasion with a 1500 pound RZR in the bed, bringing our weight to 7K. Pulled the Baker into Vegas with the RZR at 55 without issue.
