D'max mpg

Looking to upgrade truck to pull camper and looking for actual D'max users mpg's. Mpg's more important in fuel costs considering camper will only get pulled long distances twice a year and this will be my daily driver as well.

I get about 17-18 MPG unloaded and about 14-15 with my 8000lb travel trailer.

Don't judge me haha...

Towing a 13,000lb 5th wheel with my 2007 Dmax. I went south to north and back so there were some significant hills.

I averaged 9.5 to 10 MPG. doing the speed limit----65 mostly. I have an aux tank in the bed that holds 60 gallons or else I would stop at every other exit for fuel.

No mods except for supersprings.

I would find a competent diesel tuning company and have them tune it for you.

Or you can get a tuner such as banks

Have a shop that does a lot of diesel performance work tune it for you. They will almost always use efi live as their tuning software.

Yeah from what I've heard EFI live is really great. I know guys running Cummins, and Dmax, and it's great that you can have different tunes for different needs.
