Need Guidance 360 Cummins

[T2RV]

We are looking at buying a 37- 38 Newmar with a 360 Cummins. Will that tow a Grand Cherokee in the mountains?

While not a Newmar this may help give you a feel for it. We have a 40' Coachman Encore TS with a 330 hp Mercedes. We tow a F150 SuperCrew 4 WD through the mountains on occasion. We have not had issues. We do not fly up the mountains.

I had the same engine towing 8k lbs ( 3/4 ton crew cab diesel )

It overheated on extreme climbs and long consistent climbs requiring me to slow down or take pull outs.

Your vehicle is far lighter and will not be a problem.

Just be aware that you will be pretty slow on steep grades. The GC will weigh pretty close to 5k lbs curb weight (depending on model year). A NM with a 360 is very likely to have a 5k hitch. So you will have to watch how much "stuff" you load in the toad.

As stated you will not win any races up the mountains but it will tow it fine.

We have a Cherokee behind our Superstar with the 360 and it works for us. 7% grade through the Blue Ridge we did about 40 - not fast but good enough.

Thank you

I'm assuming when you say Cummins 360, you're referring to the 6.7 Cummins diesel rated at 360hp, and 800# of torque? The newer 6.7s rated torque close to 1200#.

Either way you'll have no problem going up any mountain, or traveling anywhere with your combo. I have a 2014 36' Sportscoach that was rated at 300hp and 660# of torque that I had Cummins upgrade (change computer settings, took 3 hrs ) to 360hp and 800# torque. I went from WNY to Napa along I-70 through the Eisenhower Tunnel near Denver at 11000 ft. towing my wife's Kia on a 500# dolly with zero difficulty. Going down the grades is where you have to be careful and on your toes.

More interesting, because of bad signage and Garmin directions we traveled up a 19% grade near Yosemite NP, Old Priest Rd , I didn't think in hell we'd make it, but the Cummins tackled the grade with ease in first and second gear.
