RE: Why diesels are most efficient around 1,800 rpm

We always run in 5th when towing a large 5th wheel, TT, or hauling a large, in-bed camper with our '16 Ram Cummins. Made a number of MPG calculations running in 5th and 6th while under heavy load. Very close, if not identical MPG's. By running in 5th, our RPM's hover around 1,800 RPM at 60-65 mpg. The engine (and engine brake) is much more responsive in 5th and there's no downshifting on mountain passes. If for no other reason, we'd keep it in 5th just to reduce wear and tear to the tranny (no downshifts). You understand the reason 3.42's are golden!

RE: Tire Opinions

I have been running the NITTO Ridge grapplers for two years now and I am more than impressed! US Made also. Stay clear of NEXEN's.

RE: comfortable ride in an one ton dually??

Ah, but you cheat with that air ride suspension. LOL I think that one could remove the overloads and add airbags and have basically the same as I do with the Factory Rear Air Ride.

RE: Why diesels are most efficient around 1,800 rpm

I don't care what anyone says the faster you go the worse mileage you will get. Example some say they get their best mileage towing at 67-70, I call BS.

Nice!

RE: comfortable ride in an one ton dually??

Soft springs enable a vehicle to ride well, but you won't be hauling heavy loads with it. With a 1 ton dually, it's pretty much the nature of the beast. An aftermarket seat might help with the ride, but that would be about it. Perhaps a class A motorhome may be in your future. I have soft springs but carry 6k pin easily. :B

RE: comfortable ride in an one ton dually??

Love my ride loaded or unloaded! RAM 3500 Factory Rear air ride. Truck sets nice and low for easier entry/exit. Run the rear tires 35psi unloaded. If you don't need a DRW same applies with a 3500 Long Bed. I also have a 01 RAM so I completely know the difference.

RE: Dutchman Grand Junction vs DRV Mobile Suitea

Another question is....is there a similar DRV quality build in a bit shorter 5th wheel. Were very concerned about the rear end clearance in getting a 36 or 38 footer on the property. Thanks again. DRV makes a 32' model.

RE: Dutchman Grand Junction vs DRV Mobile Suitea

Thanks. From just observation the Grand Junction looks ok. Its been well maintained. But i can tell the materials are a bit better in the DRV. Simply compare the frames. Mine on the assembly line. Two 2x6 and one 2x3 tubes stacked and welded to make a 15" tall boxed frame. https://i.imgur.com/pc7E086l.jpg

RE: Dutchman Grand Junction vs DRV Mobile Suitea

When was DRV bought out by Thor? Im assuming consensus is a drop in quality at that time? We left NW WA 1/1/15 to travel to Rolling Retreats in Elk City, OK to order our current DRV. Along the way we heard that Thor just purchased DRV. We decided it would not make any difference and proceeded with the order.

RE: Replacing furnature

I replaced my peeling furniture with Stanton that is made in Portland, OR. Good quality and good pricing. Ordered theater seating and couch/hide a bed while in CA and stopped right along the freeway and installed in their parking lot.

RE: Why diesels are most efficient around 1,800 rpm

"Also, guess what rpm a 4.10 Ram 3500 that is in 6th to get that good mileage when towing? The same rpm I am at in 5th with 3.42s. Who da thunk it....." I loved my 3.42's in my 11 HO RAM DRW. Only issue was I had to take it easy on launch on grade. Fast forward my 15 has 4.10's and AISIN. Hind sight I should have bought the 3.42's with AISIN and towed in 5th same rpms I now do in 6th. The LOW starting gears in the AISIN would have made launching 36k a non issue and had another gear for better highway economy running solo.

RE: Dutchman Grand Junction vs DRV Mobile Suitea

I own a 2016 39TKSB3 DRV. Ordered it new from Rolling Retreats with many upgrades. We full time since new. Certainly not perfect but it really is a high end RV.

RE: Why diesels are most efficient around 1,800 rpm

This is my fourth season double towing. I drive by the troopers all the time or they slowly pass right along side of me. Both WA and OR Double towing is not allowed. BUT I am licensed SD so who knows that may help. CA recognizes SD so that is why I am fine towing doubles there also. It costs $500 each way to have my MC transported. So I am to the good over 3k at this point. If pulled over I will simply separate and leave the MC and trailer with someone and continue to the next State and drop RV and come back to pick up the MC.

Nice flat section along I-5 I will be towing from NW WA to SoCal next week and will do the same test towing 36k combined. https://i.imgur.com/wvpoAAFl.jpg https://i.imgur.com/g63mwzPl.jpg https://i.imgur.com/ZhAKqlAl.jpg

RE: Why diesels are most efficient around 1,800 rpm

Today on flat ground I set cruise at 60 in 6th. Instant average was 18, dropped to 5th 15 and then 4th 11mpg.

RE: Why diesels are most efficient around 1,800 rpm

"When towing, whatever gear keeps engine rpm between 1,800 and 2,000 rpm will give the best fuel mileage and power because that is the rpm window where the Cummins 6.7-liter makes peak torque. I tow at 60 with rpm's about 1,750. Just right! That's with 4.10's. At 70 I am about 2,000. With my last DRW I had 3.42's. I would tow in 5th at same rpm's as above, just right! Sounds just right. What is your fuel economy at 60 mph and 30,000 lbs combined? How many lb ft of torque was your last DRW? 34k combined hand calc 9-9.5 West Coast. Add MC trailer drops .5 mpg. 2011 RAM DRW HO. I think it was 350/800? The 11 was a solid 9.5 at 30k.
