Question Gas Versus Diesel

Thinking about trading for the mercedes diesel engine motor home which is supposed to get 16 to 19 mpg. Diesel costs more and have heard you have to add supplements to the diesel which is expensive. What are the pro's and con's cost wise, especially since diesel costs more per gallon.

Would appreciate any feedback.

Thanks

IMHO, it depends on how big you want to go. If you find a 40+ footer with a GVW of 40,000 + that will get 16-19 MPG, let me know and I will buy one in a heart beat.

I suspect she's looking at a Sprinter-based rig.

Gas versus diesel

Yes, am looking a t the smaller 24' 25' motor homes that are being put out by a couple or more RV makers.
The motor home I have now is 24' gas Ford and doesn't get as good mileage as my 35' 2005 Holiday Rambler Vacationer with Allison transmission got. I sometimes could get 12 mpg on Vacationer doing speed limit on flat ground.
Do you have any info on these new mercedes diesels. I would love to talk with someone who has one.

AGAIN, MANY THANKS!!

I think it comes down to how many mile you drive? Must of us don't drive enough miles to justify the cost of a new unit. The difference in the cost of the unit compared to the cost of fuel is a lot of miles.

That 16 to 19 mpg might be a little optimistic, but probably fairly close. Normally, you don't need to add any supplements to your diesel fuel. If you will leave it sitting for extended periods of time, you might want to add an algaecide.

The only "supplement" I know of on the newer units is diesel exhaust fluid (DEF), which is added every few thousand miles to a separate tank; it is NOT added to the diesel fuel. It costs probably $3/gallon or less at a truck stop pump, and a typical tank might hold 5 gallons, so it is frankly an insignificant expense in the grand scheme of RVing things. It certainly does not erode the advantage in fuel mileage of a diesel versus a comparable gasoline engine.

And, not all diesels require DEF! My Cummins 500 ISM does not require DEF or any other supplement.

Nor does my 2011 Ram/Cummins 6.7L, but most others do, and even Ram/Cummins have gone to DEF with the 2013 and 2014 trucks. IIRC, the Sprinter-based units the OP is considering utilize Mercedes' BlueTec diesel emissions system, which does require DEF.

Just to make it more complicated...
This decision (24'-25' RV) cannot be made without the understanding that these "Euro-Vans" are somewhere between 9"-10" different in width.

That is a big difference when you get inside these rigs - IMHO.

Also, the Sprinter's "mid-sized" Diesel will not have the same weight capacities of the full sized US van - important if intending to tow much weight.

The future holds LOTS of these narrower rigs as the new Dodge/Fiat and Ford/Transit vans and cab chassis rolls out in the Class B and Class C RV market.

These new high-tech Diesels are quiet, efficient, and powerful...but floor plan and power is a very important part of the decision. Knowledge is power

Best luck

Must have been made before 1/1/10, so far as I know. All current Cummins RV engines use DEF, and they no longer make an ISM.

After the first 10,000 miles in my Sprinter-based Roadtrek E-trek I'm averaging about 18mpg. Have had a few days with 19-20, but that's best case on flat roads (probably with a tailwind). The cost of DEF is indeed insignificant.
