Sweet huh? Did you notice at that rpm it didn't seem to be taxing the engine at all, and felt like it could have done it for as long as you needed?The answer is........ I had to let off the gas to slow it down. ZERO problems and had much more power left. I should have gotten a larger travel trailer. I ran it at 2800-3200 rpms and easily maintained 60-65 mph (3rd gear) up the grade.
Glad you had a positive tow.
