Cummins 350 compared to 370 for power towing

Thinking about upgrading to a new model Class A, currently have a 2002 Dutch Star with a 370 Cummins, 6 Speed Allison Trans. Happy with the power it has. Looking at a 350 Cummins, 6 Speed Allison Trans, Monaco Camelot 2005. My concern is towing power with the small engine? Any comments from experience is appreciated.

My question would be, What is the torque difference between the two. Our Cummins with 950 lbs of torque and Allison 6 speed tows our Sonata just fine. 330 hp

What motor? ISC or ISB? The torque will be different depending on what motor it is

no worry with 350 power. my isc 350 tows just fine even on steep streets like san francisco and hermantown, a suburb of duluth, mn. unless you were to tow a super heavy toad, there should be no concerns.

The best comparison tool is weight per Hp. RV manufacturers figure about 100 lbs/hp as a baseline for engine power, with less weight/hp for higher performance models (usually an optional engine). If the Camelot is the same or greater weight than your Dutch Star, it's going to be a bit slower on the hills or accelerating. Maybe not much, though, since neither one is a race horse.

If you were worrying that you might not get up a hill, no need to. At worst it might be a few mph slower.

Only concerned I see is, most 370 HP that I have seen are ISL around 1200# torque. If they are both ISC then there will be very little felt difference.
