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
You may be right but the larger Palazzos do get the same engine with 340hp. I would be surprised if there is any real difference in the engines other than the programming (the same goes for the 6kw quiet diesel that also comes in a 7.5kw version with virtually the same specs). Getting it reprogrammed for more power would be technically possible but I doubt that Freightliner would do it. Also, I thought the that 340hp motor comes with the Allison 2500 series transmission but I could be wrong on that.
I am going to say that the performance of the Palazzo is better than you think. I also own a 33.3 and have had it in the Rocky mountains pulling a Taurus where it did reasonable well. As I recall it was able to hold 4th gear on all but a very few hills.
