I have a 34 Holiday Rambler 2006 with the 300 ISB and I tow a Saturn Vue which weighs about 3000 pounds. Most of the time I do not know I am pulling anything. And to be honest I don't know how much difference pulling the Saturn would make on a 6% grade. I do know that a long 6% grade slows me up from 60 to 40. I have never felt I was not going to make it as the transmission down shifts and just keept on "Truck'n". I drove from Phoenix to Flagstaff on I-17 and there are some long steep hills some 6% and I made it without problems. What I don't care for is going down steep grades and I am very thankful for the engine brake.
