My current truck came with the truck cap that's on it and I agree. I use my truck for work purposes in the summer so the cap needs to come off for that. But I'll put it on and off a few times during each year.

What I need is a way to take it off and put back on that is much easier. It's suffered much scratching and corner damage from being placed on the ground. Still looks good tho and is great to have covered/locked storage.

 

We get around 17 mpg empty and 12 mpg towing our 35.5 TT. 2003 Excursion V10 4X4 3.73 Diffs k+n filter and straight through exhaust.

 

WOW! 17 empty and 12 towing a 35.5' tt? is that miles per gallon or kilometers per gallon?

 

MPG my friend. And thats on LT285/75R16's. I run my programmer on premium setting and use Regular unleaded fuel.

 

One time I saw a leprechaun riding a unicorn.......

I'm just kidding. It would be amazing to achieve those numbers. I just never have or will.

 

Not sure how I got so lucky!!! Blessed me with that one! Atleast something is good out of the deal. PO was a Chiropractor not a mechanical bone in his body!!! Very poor maintenance record on this one!!! 180,000 miles on original u joints on rear.

 

That's nothing short of amazing mileage. Is that hand calculated or from the Lie-O-Meter in the overhead?
What does that 35.5' TT weigh? Our 41' TT tips the scales at 11,000lbs.
Is that unleaded regular mixed with corn liquor? Nearly all of ours down here is and it hurts the mileage some.
What tuner and tunes are you running? We use 5Stars Custom Performance tunes both 87 and 89 Octane for all of our towing.
Is the terrain mostly flat where you are seeing that mileage? Here in the Eastern US I can't go very far without climbing some Interstate Highway grades (unless I head due South!).
We are seeing between 8 and 9.25 MPG towing our TT with our V-10 EX running a 4" lift with 35" and 4.88 gears (effective ratio of 4.39) using the above mentioned custom tunes and Banks headers and stock exhaust. Unloaded I get 13-ish highway MPG.

 

Tank to tank on the lie meter. TT weighs 9000 lbs. Not sure what its mixed with. Its a procomp tuner, I run it on the 92 octane tune!!! Somewhat flat here in southern Alberta, British Columbia and Montana about half hour to an hour out. 3.73 diff's help!!! V10 is an awesome engine for torque pulling power. Anything better than my 01 F250 with the 5.4 at 13 mpg!!!

 

I would suggest that you do some hand calculations to see what your actual MPGs are, Between the slightly taller tires and the tunes the overhead may be a little off. All of my numbers are hand calculated.
The pulling difference between my factory 3.73 gears and the 4.88s is huge, with the stock gears and a 9,500lb toyhauler behind we were getting 6 to 7.5 MPG on the relatively flat (some rolling hills) I-95 trip to/from Philly and Savannah. The trans would downshift on any slight grade at highway speeds. After the gear swap (with 32" tires shown in my signature pic) over the same route with the same load at the same speeds we got 9 MPG. The big difference was that it didn't downshift a single time at speed, those miles traveled in 3rd gear and high revs really knocks the MPGs down.

 

still averaging 8.5 and loving every fuel sucking second of it.

 

Lie-o-meter = leprechaun riding a unicorn

 

With the price of gas recently (71.9 cents per liter) I may actually be able to fill it up again and check it!!! Probably check on holidays to B.C. in July.

 

A few years back on a 2400+ trip in our 01 E350 15 passenger we averaged right at14 mpg. Mix of city and highway driving.

Sold that last year along with our travel trailer and replaced it with a 29ft class C motorhome with the V10. We seem to be right around 9 mpg on our trips.

 

2009 F350 CC Dually Longbed 4:10 gears with 30000mi. on the clock, empty around town I get from 8 to 10, Highway empty I get 10 to 11 (I did get all the way to 13 once.) . Loaded with My GoldWing and pulling our 9000 lb travel trailer lowest was 6 highest was 9.

 

You should check to see if you have more than 2 injectors firing What is the theory behind running the tuner on Prem BUT burning Reg ?? I can't think that is to good on the engine ?? If it got me an extra 7 MPG I'd probably do it to though
