FWIW I have never felt short on hp driving the coach. Not surprising as the 350 hp engine pulls F53 based MHs with double the weight.

Interesting comment regarding “Economy” engine. I did not consider it a possibility that would explain your higher fuel economy because Thor specifications only listed power and torque ratings of the “Premium” V8 in their specs.
For smaller and lighter motorhomes the slightly less powerful engine makes sense if it can deliver the kind of fuel economy you are getting. Just wondering if your Economy engine was a fluke or if there are others in motorhomes? Power and torque differences are less than 10% so most drivers probably wouldn’t even notice the difference.
