Diesel mpg
 
Now that others told you what the mpg is. Can you afford it?
I have seen post where people ask about a fuel budget.
If you have to ask, maybe you cant afford it.
We have a 2007 bus. Bteak downs are more of a concern that mpg.
Had are bus for 2 years and extended warranty has pad close to $10,000 in repairs.
So, my personal opinion is that.
Good luck on what you decide!

I think the question is certainly a valid one and one of interest to us as we find our current mini Class A a bit tight and were pondering a move to something a bit larger. Not everyone is rich enough to not care about the cost of traveling and most of us prefer making an informed decision whatever the topic.

For us, the less it costs to take a trip, the more likely we are to take it. I've owned a number of power boats over the years as well as a few hotrods and the cost of using them is always a consideration in how much or often.

This is our third motorhome and by far the most economical. It's an Itasca Reyo, 25' with two slides powered by a MB V6 turbo diesel and yesterday I averaged 14.5 at 65 towing a trailer with golf cart and it will get over 16 if not towing something. I joined a Yahoo group for these coaches before buying it and when I first read some of the members claiming 16-17 mpg, I wanted some of what they were smoking but now I'm a believer. Moving from this kind of mileage to something that gets half that wouldn't be done lightly.

Our first coach was a 34' Allegro, no slides, front engine Cummings and got 8-10mpg never towing anything. It wasn't great but at the time we only planned on RVing for 1-2 years max and the coach was a good deal used so we didn't concern ourselves too much about the mileage. Next we had a classic GMC, 26' with gas 406 Olds and it gets 10+ without towing anything. Ended up not using it much as the reliability of a 40 year vehicle isn't that great.

Now we'll take day trips all over the state without a second thought. I doubt I'd fire up a 38-42' coach as willingly.

2 different coachs, 2 totally different mpg
 
From 2004 through 2015 I had a 2000 Monaco Dynasty 40' w/Cummins 350 ISC towing a Cadillac Allante on a Demco tow dolly I drove 76,000 miles and consistently got 9+ mpg @ 65 miles per hour in every terrain in 48 states. In fact the lifetime engine mpg was 8.9 which included idle, maintenance and test drive times. It DID NOT have a tag axle.

From 2015 to the present I have a 2007 Monaco Dynasty 42.5' w Cummins 400 ISL towing the same car on the same dolly on many of the same roads at the same speeds and I feel Lucky if I break 6.5 mpg. It HAS a tag axle.

True, I have only driven this coach about 10,000 miles, but for mpg, it does not look good.

However, this coach rides better, handles better and stops better. I guess you have to decide what is more important for you. Do you get the most value or the most comfort.

Happy Motoring,
Art Perrone

Guess I'm not doing to bad
 
2006 Prevost conversion 51,000lbs+ with full fuel and water tanks towing a fully loaded Suburban from NY to FL through the hills of VA and PA at 65-70mph I average 6.1 for the whole trip.

MoparHauler 01-25-2019 12:29 PM

I'm surprised more people don't get 10 mpg. I can average 10-10.5 mpg in Ohio and Indiana pulling a 26' trailer. BUT....put me Western Pa.,West Virginia, and some hilly areas I only get 8-8.5 mpg. I rarely go over 65 mph. Even my old Winnebago Vectra would average 9 mpg towing and 10-10.5 mpg with no trailer.

Cat C13 (525 HP) towing hybrid sedan just under 50,000 lbs combined usually 62-65 and average about 24 mpg on a trip. Sometimes a little more depending on how many local sight seeing side trips. This over last 50,000 miles ... Coach about 6, car 42 so averages to about 24 mpg. ;-)
