Fuel mileage?

[Mike Canter]

I am only at 1420 rpm at 62 mph on my Detroit motor. An update on my MPG. I drove from Atlanta to Tampa and back at 60-62 mph with following winds and no hills other than overpasses in Florida. Whole trip average was 6.9 MPG and that was pulling the Jeep Wrangler. It sure makes a difference not having headwinds or hills/mountains.

The last few posts illustrate intelligent, honest and accurate mileage reports; but more importantly they show why diesel must be the choice for really any motorhome; there is a direct correlation to low fuel consumption (relatively speaking) and low engine revs.
Each of the recent posts show a rate of consumption on par to what I know most C gassers are acheiving while doing at least three times the amount of work.

Mr.D, no chip on my shoulder at all, I stated that I like the A coach and that I like the A people we have met, heck I even like the A people we haven't met and I have even said that I like rich people because rich people give people like me, jobs. I cannot afford a speeding ticket nor can I afford to drive at any speed higher than one which gets us the most gas mileage.

People in big rigs generally have attitudes to match, MOST people in an A coach can afford to be in these magnificent rolling homes and as such speeding tickets are not a concern, and good for them on this account also.

This bugs you and my intent was not to upset.

I see where your going with that Rough Road but my experience is a little different here in the midwest. I run into mostly older couples that drive very slow in many cases and are a real treat to meet at the pumps, campgrounds or what ever.
I certainly can't really afford my class A but since I love it and use it so much I find a way to make it happen. I have seen the more caustic folks out there but they are there in any facet of the world and not limited to class A motorhomes... I get your point though.

Regarding the lower RPM, well I guess that is a shot at getting better MPG from Monaco. The upshifting early thing is annoying though, I wish it upshifted a little later for better acceleration onto the highway.

Also, my comments earlier about MPG need further input. I am a tightwad when it comes to fuel so I really try to plan things for best MPG/arrival time I can. I try not to run the Aqua hot on burner unless I have to and running the generator is when needed only, not a 24-7 thing like other dry camper folks do. That Gen really cuts into the MPG cause it is just too big IMO. Ive only put about 1400 hours on it in 4 years with almost all dry camping...

Slightly off topic, from the already off topic...
I drive the snot out of my MBE926 motor. I'm the guy you're talking about driving fast. My coach runs up and down 'Parley's Canyon' two round trips every time I take it out. You can't really call that pedal on the right an 'accelerator.' I guess 'throttle' works.

I take the RV to go race cars and karts with my son every other weekend, and tow a trailer. Vacations see a Jeep toad back there. It will hum along at 75 pretty easily...yes, for me it's a race, but I know the limits of the coach. The highest RPM is with engine braking, not cruising down the road. Running synthetics in all the right places, change hub oil, diff, lots of filters.

To and from a race track, 7.3mpg, most of that is caused by the long uphill from Salt Lake. Family trips 8.3mpg, even better if we head north instead of south. Fuel mileage is very trip and driver dependent, sometimes caffine and time of day dependent. I'm not retired, I'm in a hurry, a hurry to get somewhere to do 'nothing.' Where nothing is camping, hiking, racing, meeting people, drinking, swimming, taking photos, shopping, cooking, or fixing something. On another forum, there are guys getting nearly 10mpg in the MBE motor (more torque than the c7) if they do that 62 mph thing. There are sections of road in Utah with 80mph speed limits. I don't feel like driving that speed with my hazard lights on...it's bad enough having to do it uphill.

Ditto what someone said about getting an earlier engine without DEF, you have to figure that expense in if the cost is a concern. For me, it's the ability to burn Mexican diesel...not everyone has ULSD.

Anybody here ever get a speeding ticket in an RV? I've thought about that, but will anybody admit it? I figure, if you can afford a diesel, you can afford a Radar detector.

Used diesel A's/super C's seem to be selling at a premium, at least in our area.

I agree on the geting a older unit. let others take that big value drop.
I really like my 94 cummins powered Ford.

No one that I know of. But I stay out of California. I would think it would be most likely to happen there if it's going to happen.

A good friend was driving a Class C up the Oregon coast in a CruiseAmerica. First time driving a motorhome. Yep. Busted while passing traffic.

windecker, it I could con some lender I would get something now, smaller than yours but with some hp so I could stay ahead of the repo guy-hope you get to enjoy yours for a million more miles...

[Windecker]

I have two friends that have. One lives in Chicago and got busted for 85 in Texas. He said the Cop was NOT amused (and I understand). Another buddy lives in Memphis and got hit in Texas for 73 in a 70, once again the Cop was not amused. Said the Cop said "what don't you understand about the word Limit" LOL.

Thanks! I am younger than most with a Class A DP, (46) but use the heck out of it and appreciate it very much

Preparation, driving location, and driving style all contribute to fuel usage.
10.4 mpg from our 8.3c DP for 2011.
Reasonable driving in clear calm conditions to driving into a tropical storm.
Mountains to the shore and everything in between..
I am considering upgrading the injectors if it would improve our fuel efficiency, anyone tried some of the injector rebuild services that claim large percentage improvements in power and mileage?
thanks
