Real life MPG numbers wanted.

[krj]

I finally have some number to contribute to this thread that I started!
I recently sold my 2003 Tundra and 1988 FWC Grandby. For what I got for those, I bought a 1999 3/4 Dodge Cummins, QCLB, 5spd AND a '95 Cascade 8.5' hardside camper.
With the old rig I was getting 13mpg. First trip with the new setup and I averaged 15.5mpg. 660 mile trip, hand calc'd, mixed city and highway. First half no faster than 60mph or greater than 1800rpm. Second half, bumped it up to 65mph (2000rpm) on the highway and mostly into a head wind, no change in mpg. Diesel is now 10 cents cheaper than the premium that I was running in my Tundra! Oh yeah, I no longer have to deal with the pop-up!

This was my first trip with this configuration, so the comparable data is thin, but here it is:

2001 F250 v10 4.30 gears, crew cab shortbed 4x4 with brand new 255/85/16 KM2's. Camper weight is unknown, take a look at the picture and guess. Trailer is light and can be lifted and moved by hand. Truck had 5 passengers weighing approximately 620 lbs. Route was approximately 1000 km round trip from sea level over the Cascade Mountains driving the Coquihalla Highway (elevation 4068') and the Coquihalla Connector (elevation 5760') to Summerland in the Okanagon (elevation 1490') and then back. For the most part, speed was a consistent 95 kmph or 60 mph.

Mileage there was 8.7 mpg or 27.1 L/100km and 9 mpg or 26 L/100km on the way back. As a point of reference, I have done most of that route without the camper or trailer in the dead of winter with 235/85/16 tires and averaged 13.5 mpg. FWIW my numbers are not corrected for the larger tires.

edit: okay, my rudimentary calculations put the corrected numbers at 9 mpg or 26 L/100km there and 9.5 mpg or 24.9 L/100km back.

Good to see you are getting some time away Todd. I have obviously forgotten my days with the 460. 9 mpg is scary, but with the Coq in the calculations, not really a surprise.

[BCHauler]

Yes, curious to see what flat mpg would be. Unfortunately, not a lot of flat here in BC.

How are prices of diesel vs gasoline up there? Diesel has dropped down below mid-grade gasoline down here. At least in MT.

[redthies]

In the south coast area of BC (Vancouver), reg gas is $1.36 per liter, and diesel is at $1.32. That translates to $5.17 per US gallon for gas, and $5.01 for diesel. Premium is $1.54 or $5.85 per gallon. National average for reg is around $4.50.

Canada is one of the largest suppliers of fuel to the US. Makes me wonder why we can't get it for at least the same price, if not significantly less up here. But I won't think about that too long, as it makes me think of ways to torture oil company execs, and govt tax collectors...

My 97 F350 with PSD auto is getting 18.2 mpg mixed driving with a heavy foot. This is with a shackle reversal that has me about 3" over stock, and 35" Toyo MTs. My only longer trip with the camper on was over some incredibly high and long mountain passes, and I got closer to 12-13 mpg. The camper is a 10' Adventurer 10T (2007). We are going to Hood River in 3 weeks, so I'll post up mileage numbers after that trip. I'm hoping for at least 15 mpg on I-5 at a steady 60 mph. Fingers crossed!

8.5-9.3 mpg on pavement at 60mph. Maybe not too bad for loaded weight over 27000 lb, cross section is 12'7" tall and 7'10" wide, 5.92 gears, portal gearboxes and 47" tires.

Charlie, with a Unicat on a Mog, fuel economy probably shouldn't be a big issue

[duneyeti9]

F350 6.7 PS with a Lance 835 and towing a wrangler I get just over 12 if I keep it under 70. Without the Wrangler I have never gotten better than 14. Of note I get 21+ with the truck empty. I’m just shy of 5,000 lbs per axel with everything loaded and full tanks. These #’s are from the onboard computer but I have hand calculated and my #’s were always within .5 of the computer so it doesn’t lie too bad. I travel mostly in the south east US and Texas, not many mountains.

Good to see Charlie adding some balance!

My mog is 21000lbs, 13' tall, and also does about 8 miles per US gallon

But, diesel in the UK has just come down to about £1.30 per litre if you shop around, £5.90 per UK gallon, £4.92 per US gallon, or $7.65 per US gallon today at £1 = $1.56

Its interesting to see how many people on this forum assume everyone here is from the Americas, so no-one thinks to mention which gallon you're using

Similarly, in comparison to a mog, how many haul such a lot with relatively small trucks but still get similar mpg. If everyone here had to pay UK prices for fuel how much smaller would both what you take with you, and how big a rig you have, become?

What will the typical camper rig be in 20-30 years time? Horse drawn?
