On our first trip we drove almost 600 miles and averaged just over 8 mpg checking tank fillup not by computer. I know as have owned both, Towing you will get 6-7. At best those mods except for 3, which will do nothing will increase power. I got as high as 15. We drive 200-300 miles per day, then stop early, and stay awhile if we like the area. We started out flat towing a Jeep Wrangler, but now have an enclosed trailer. What has happened with the diesel engine and the emissions controls has caused major changes to the diesel industry.
I tried to call Fleetwood but they are closed. We also us a lot of back roads and two lane roads to see more things which help with the fuel economy. The maintenance costs from the diesel emissions control equipment is negating almost all economic benefits of running a diesel versus a gas engine without considering upfront cost, since there is no gas option from Mercedes. Within the last few weeks, I have been checking my mpg. We lay at a solid 9. Best wishes though on your future adventure. So, we all can do some do some things to improve the mileage of our rigs.
The class A Gas were great coaches but never got better that 8. Tour buses, commercial trucks, passenger buses all tend to be diesel. I do not drive over 60 mph mostly 55. I also, had business in 9 states! Though I have researched improving the aerodynamics on them, and there are owner tweaks that can be done to improve efficiency by 3-4% areotabs, removing projections, underbody covers, etc. Can you, or anyone, recommend the best way to go? In the climb up a hill, down a hill? Off to the side I have a ram 5500 truck with a cummins that gets 7 mpg compared to similar truck but older, a 2001 2500 ram with same cummins that would get 20 mpg.
Empty I should weigh close to what you do but I will have a 6. We tow a 2007 Lifted and optioned for off road Jeep Wrangler 4 door. I have spent 18 months doing research but you switched from deisel to gas. Aside from referring them to your reporting on your site, the onboard computer currently shows 12. Pretty sweet little app, which track most of your metrics contained in your post.
With 80 Gal of Fuel and 60 Gal Water. From Colorado Sprinkgs to Oklahoma City we had an avg mpg of 9. It has a V6 engine and gets reliably 15 to 18 miles per gallon. Keep the tires properly inflated. First start off with air pressure of my tires. Diesel is the only way to go with something this size I think. The information is sent to the computer and the timing will be retarded until the knock pre-igniton is eliminated.
I have been following your journeys and blog for the last year and your current adventure is really interesting as we followed almost the same route, as you, when we went to Alaska in 2012. I tow a two door Jeep Wrangler that weighs just under 4,000 lbs. Thanks for your updates and blog posts! Given that the savings would increase dramatically driving a diesel pusher. They want to know where you live if you stop paying for it so they can come over and repossess it. Just driving 65 mph instead of 80mph will save you a considerable amount of gas, will induce less engine stress, and keep you safer.
When towing I average just under 15 mpg and when not towing average a little over 18mpg. In the far future I would love to see an hybrid-electric drivetrain with multiple gensets driving electric motors for redundancy and scalability. They were build in the 70s so most are 40+ years old. Pay attention to wind conditions and go slow when into a headwind. If the engine won't crank, you…. Check with your dealer for exact monthly payment.
I get around 7 and 8 with my class C gas. Maybe you two could use your connections to find out the cost of the two chassis. Once again the family grew and u traded it in 2015 for a 2016- 32 foot forest river bunk house. So when approaching a hill say in a 90km zone, speed up on the flat or downhill before the incline by 10-15 kph to give you the momentum to clear the hill without downshifting. Doubtful you would get anywhere near this. This is the worst engine trans combo ever!!!! Install a throttle body spacer. I was considering a Tiffin Allegro with Ford gas power.
