I'm running a 2014 Thor Palazzo 33.3. It has a ISB 300 and Allison 2100 MH. I could go to ISB 340 / 700 with the same transmission. I have towed a 2015 Suburban, 2015 GMC Acadia Denali, 2016 Yukon Denali XL, and 2017 Ford Explorer. The I am at my max GCWR when I tow the Yukon and the motor home is empty. The transmission does downshift. I have traveled over the rocky mountains 4 times with this setup (pulling the Acadia) we had no problems. I probably will upgrade to ISB 340.
Are you planning to upgrade the engine that you have? How do you plan to do that and how much do you expect it to cost?
LOL Iam pretty sure he means upgrade to a mh that has more power because the
300 ISB towing a Denali xl 4x4 will be in 2nd gear at 25MPH going over mamouth mountain type passes LOL
frankly get he 360hp if your only going still with a ISB
