I have stock size tires, 2WD and weigh in just under 9,000 lbs wet (all tanks full, my stuff, no people.) The SCT Live Wire tuner ("TOW 50" setting) gave me almost 2 MPG over stock on the highway. I can't really see any difference in city driving but the throttle is more responsive.
2wd and an SCT; definitely good for the mileage. Personally, I'm not ready for a tuner so I don't jeopardize my warranty, but it's very tempting. The 4wd probably costs 2 mpg or more.

I'm probably averaging 15.5mpg all told. With Interstate type driving at 60-65mph with little stop and go, I'm getting 16.5 to 17.5mpg. On winding secondary roads it's down to 14mpg, and in 4 wheel drive in the backcountry it drops to 12-13mpg.

I've got 10,000 miles on the rig so far, with the first Amsoil synthetic oil change, and running 265/75 16 BFG AT-KOs. All mileages are fully loaded with two people, two labradogs, trojan front and rear bumpers, a full load of 20 gallons of water, and nothing on the roof.

Nearly idential to my experience. We have 20,000 miles on our van with an avg. MPG of 16. For long road trips at 60-62mph, I usually get 15.5-17, with best ever of 19.2 on an 330 mile trip. When I tow, the MPG drops to 12-13, with a load about 5000 pounds. Average driving speed has a big impact as does terrain.

Can I just say that TwoLost, you are out of control !! I love your datasets, your extreme attention to detail. Only you would have it graphed !! heh...

With the V-10 I find that I get 10-12 pretty consistently, in almost all driving situations, loaded or unloaded, on road or off. Even routinely see 11+ pulling a 15-foot Boston Whaler (1500lbs) on occassion.

I might see 10mpg if there is a lot of stop and go involved, but rarely if ever below 10. I have seen 13 and thought I hit 14 once, with a light load and a tailwind (and wishful thinking). Once. But I am very conscious of the fuel use and drive accordingly - using cruise, etc wherever possible. Its 10-12. Almost without fail. City or highway, offroad or not. Running BFG 285 75 16s.

Back from Baja, first real mileage test and it's not so great. Average around 12 for the trip. 10 was the lowest and 13 the best. This is towing about 3000lbs and loaded to the gills on those twisty Baja roads. Hope it gets better. Before the 4x4 conversion I had one tank of 18 from Houston to Tucson but doubt I'll ever see that number again.

Thanks everyone for responded to my question. I just took a mph reading from my GPS and realized that my van speedo reads 2 mph slower than my gps. gps reads 62 mph while van speedo reads 60. I will take a new mpg in my next filling.

MPG

We have a 97 Chevy 2WD RB 5.7l and get 16 - 17 MPG on long trips. I generally obey the speed limit (+1 or 2 MPH) and try to drive to maximize mileage. Around town I don't even calculate the mileage as I don't want to know, but its probably around 12.

Re: how many miles per gallon do you get?

We just drove from Austin to Massachusetts after picking up our used 1999 Dodge SMB and got 14.5 most of the way. Not overly loaded, just 3/4 full water tank and propane. But this included driving through 50 mph cross winds in VA that nearly lifted off our penthouse.

We found our spedo was reading 60 while the GPS read 62.

M.P.G.

I got 13.2 mpg on a trip to Death Valley in Nov. setting cruise on 65 as much as possible & stayed at Mesquite Springs. Second trip Last week, cruise on 50 to 55 while on US95 and considerable driving in the valley, mostly on pavement, got 15.3 for the entire trip. It helped to travel with friends in a 1977 dodge class C motorhome which will do 60 in a powerful tailwind. I have a standard E350 with a PH top & nothing particular heavy in it.
