I just got back from a 1500 mile trip, pulling the 5er about 1100 of those miles.The set up is as below in the pic, and the 5er is 37' and weighs around 11500#. I have weighed it several times.Truck mods include a 4" exhaust with muffler (no cat), and a Hypertech programmer set on level 2 out of 3. Intake is stock with the 4" pleated paper air filter.I checked the mpg over 5 tanks during which the whole fuel load was used to tow. The terrain was mostly flat with some mountain passes at the end, and there wasn't much wind (rare).Tank 1: 21.58L/100km = 10.90 mpg (USA gal)Tank 2: 21.42L/100km = 10.98 mpgTank 3: 20.45L/100km = 11.50 mpgTank 4: 21.06L/100km = 11.17 mpgTank 5: 19.69L/100km = 11.95 mpgGcw (truck & trailer) is about 21000#

That is terrific mileage towing nearly 6 tons!My F250 sees those kind of mpg- in heavy-footed city driving (NOT towing) LOL Awesome pic BTW

If your combination weight is 21,000 and your trailer weighs 11,500 of that then your SRW truck weighs 9,500 lbs? That seems a little steep even for a dually let alone SRW. The reason I bring this up is lately I am seeing a lot of people say their trailer weighs Y and their combination weight is Z but Z-Y= a number that seems too large for just the truck. Is everybody simply taking the trailer axle weight and saying that is the actual trailer weight?

Well I just got back also IB. I was right at 22k after importing some products from Cali :W but mine wasn't as nice as yours. I finally got a gas app on the phone and boy is that DIC off. About 2000 miles total towing and 987 bobtailing. These were my numbers in US gallons .15.739.86 11.316.5917.3312.8715.0814.229.9513.6Oregon coast highway into the Redwoods and back through Bend. Pretty good passes like Deadmans, Cabbage hill and Lewiston grade. Not sure if rain matters but the 9.95 was a total pull in the rain.

Is everybody simply taking the trailer axle weight and saying that is the actual trailer weight?Must include pin weight as that truck should only weight around 7,500# unless there is a aux fuel tank or something in the bed. My F350 is 8,200# 39 gal fuel and people (800#) loaded to go. I gross 20,000# and get 10-12 mpg depending upon terrain in Tow/Haul mode.

18.5k loaded from N VA via WV, KY, TN, IL, AR, OK, Belen NM via Santa Rosa and Vaughn. Belen-Creede CO, Creede-ABQ-OK-VA reversing via KY. 10. 8 MPG and went down to 9.6 from OK to VA. I have a 100 gal capacity and bought Phillips petroleum fuel and it seems to have a lower cetane but was 3.52/gal. Chevy Duramax, turned up to 385 HP.

Truck had 150# genny and spare LPG tank in the bed, 100# dog and 5 people in the cab, etc...

When fully loaded and hitched up, the truck comes in around 10,000#.
So this includes the pin weight?
Yes.

Last time I actually weighed the whole combo all hitched up, then unhitched and weighed again, the RV was just over 11,300# and the truck was 10,000# loaded & hitched, 7800# loaded (genny, LPG, 3 passengers) and unhitched. Pin weight was around 2200#. Going from memory, so all numbers are approximates. I also have to convert all my scale weights from Kg to lbs so my American friends can make sense of them :) so they all come out to odd numbers.
Again this tells me that the trailer itself weighs around 13,500 if you include the pin weight which is actually part of what the trailer weighs, not the truck.
Trailer is 11300 - 11500# by itself, 9100 to 9300# axle weight plus 2200 pin.

The truck (without passengers, 5er hitch, and cargo) weighs ~7300# last time I scaled it.

Tomato/tomatto I guess, but the 2200 lbs is part of the trailer's actual weight even though the truck ends up carrying that weight. If the trailer wheels only carry 11,000 lbs and the pin weight is 2,000 lbs, you are still towing a 13,000 lb trailer.

Did ya ride the big bus, ib?

Heading to Jasper mid Sept...favorite time to go, less crowded.

That's an older pic, just used to show the combo. But yes, I've been on the glacier a few times. Never gets old riding in a monster truck bus!

And watch where you walk :E Those cracks are scary. Those buses have the " hydro static" type transmission I believe. No input from right foot, no output reverse or forward. They have them down in Patagonia as well as Tories de Paine in Chile and Antarctic. Of course the flight in was the truly scary part.

Every truck is different, put bigger wheels plus the many accessories available and weight adds up fast, i have over 15000 dollars of add ons, 06 cummins 4x4 ,SRW, scaled at just over 8100 lbs just me in it,likely closer to 8200 now,even though i,ve personally lost weight.
