sportmobile fuel mileage?

[Ed in Montana]

I'm getting around 15.5-16 mpg average after 10,000 miles on our diesel SMB. I get as high as 18 mpg with interstate driving at 65mph, and as low as 13-14mph on gravel and in 4 wheel drive. The SMB has nothing on the roof along with 265/16 BFG AT tires.

It is remarkable how much better the mileage is cruising at 60-65mph rather than 75mph. Don't know what it would get in town with stop and go traffic, since we don't have much of a town.

Just for comparison's sake, I have a '99 F250 4x4 ext cab with 7.3 TD and Lance Lite cab-over camper. At 55 mph we get 15-16 mpg and at 65 in the mountains or 75 on flat interstates we get 13.5-14.5 mpg. Without the camper we get 17.5-18 highway and 15-16 in town. Also I can pass anything anywhere on the highway. Typical weight on commercial scales with the camper is 9,900 lbs!

Nearly 30k miles and averaging 16-16.5mpg on the highway cruising between 60-62mph. City and mixed driving or towing the mileage drops to about 13-14. This is an 06 SMB 4x4 PSD.

My van's not a Sportsmobile, it's a Pleasure Way Traverse which has a Westy conversion (like the RB-50). It has flat plate hot water, a 5k BTU A/C, 12 gallons of fresh water, and a 16k BTU furnace. Has the little Norcold (2.7 cu ft) AC/DC fridge, microwave, and two burner cooktop. I run two Grp 27 105 amp batteries and carry a Honda generator when I feel I need some backup.

It's standard drive with the 5.4 V-8 and 3:73 axle. I average 17 MPG.
