11.6 MPG's ?????

[The patriot]

I took the TT to Lancaster a few days ago. Got back and filled up. 11. 6 MPG's!!!

Now I freely admit it, I was pretty much tromping on it. I dont tow much, so I wanted to de carbonise it. As long as it would build speed on the hills, I did. About 65-75 on the highways.

Does this sound right? We dont have any big mountains like out west. Really just some big hills. I dont believe there was one that I couldnt get into 5th into on.

Question is, does this sound right? I'm thinking I should get the timing done.

Oh yea, this was with the 98.

What does the trailer weigh?

Eric:



That's similar to the fuel mileage I get towing a trailer. My TT is a 32' Avion weighing about 8500#. If I run 70, with some hills, it will average about 10 to 11 mpg. If I slow down to 60 it will do a little better but it pulls so easy at 70 mph, I usually don't.



Cummins engines are powerful and economical but they are not smart enough to overcome the laws of physics. It takes fuel to produce the power to pull a load fast and TTs do push some air.



The CTD does about 40% to 50% better than the fuel-injected 460 Ford I had before I bought the Dodge Ram and the Cummins holds speed on hills so I'm not complaining.

Not too bad for whomping it

Patriot - That doesn't sound too bad for the way you mentioned you were driving.



My 5'er has the tallest front area that I've seen. Its 6' tall inside height in the front bedroom. Under the best circumstances for me, I'll get about 11. 25 mpg. That's around 67 mph, flat country, and all interstate.

I towed my TT from Syracuse to WInchester VA (through PA on RT81) I got 10 - 11 mpg doing 70mph.



Sounds about right.

Trailer is about 7000 loaded. The front is somewhat sloped (see my photo album) so this should help on the highway.

Reason I asked is, I towed the last trailer to Ohio, and I got about 3 Mpg's better. Granted that was a smaller trailer, and it was 100% highway miles. When I did this, I set the cruise on 80 the whole way across Rt 80 through Pa.

I suppose this trailer is a bit heavier, and I wasnt on "the road" the whole time this time.

I gotta be a little easier ot it next time.

Thanks for the replys.

Sounds about right. Our tall 36' 5ver weighs 13,500 lbs, and we're hitting the road at 21,180 lb GCW (21,500 lb GCWR). At 65-70 MPH through mixed flat and hilly terrain, we get around 10. 5 MPG. Our V-10 pulling the same 5ver over the same route got 6. 5 MPG.

I did my first test tow (other than around the block) of my 5th-wheel with the new truck last weekend. 88 miles up to St Augustine, refueled, weighed it, then 88 miles back and refueled again. This was empty--putting the Jeep and gear inside will add another 5,000 lbs or so. This trailer is pretty tall with flipped axles and LT235/85R16 tires. I'm hoping I'm paying all the penalty I'll have to just due to aerodynamics, and that the additional weight of the Jeep won't bring the mileage down much more.



Speed: 65 MPH

Tire pressure: 70 psi front, 80 psi rear

Weights (steer/drive/trailer/GCW): 4560/5840/6960/17360

Fuel mileage: 11. 2 northbound; 10. 2 southbound

11.6 is about right

I pull a 27 foot Play-Mor 2350 Aero TT with my 1996 five speed. Limiting my speed to 65 mph (due to crap trailer tires), I usually get an overall average of 13. 2 to 13. 4 mpg. This is measured over choppy terrain and crossing the Rockies in southern Colorado. If I cut back to about 55 or 60, mileage will go up. Conversely, it'll drop further at 70 plus.



So, as you describe your driving and yuour towed load, 11. 6 is about right. Not bad, really. My neighbor pulls a similar load to yours (a 31 foot Prowler) in a similar manner with a 2000 Furd V-10 gasser. He's thrilled to get 6 mpg. He'll even offer me a beer to celebrate 6. 5!



Share and enjoy!

Towing my 15K lb Teton back from Muncie I got 10. 61 MPG. I was upset. Towing my work trailer which weighs 14K, I got 13. 4. That made me happy. The only thing I can see that is very different is the frontal sail area. The Teton is very tall. The truck had no trouble towing it, at all. Just takes more power which means more fuel. That was at 68 MPH. I have a Traileze wind diflector and some air tabs installed. Still that's what I got.



I wonder if a 4:10 rear would make a difference?

FWIW, I got just over 11 mpg towing my 5er from Tucson to Denver and back. I ran between 60 and 65 MPH. 1800 miles.

 

[Bug Out]

Hmmm..10-11 or 12MPG ..good stuff

I pull a 15,000# 5th and if I drive right, I get 11MPG or so.



Now going to Reno and trying to pass big rigs on 6% grades, i dip down to 8 MPG or so.



Not bad for 22,000 GCVW or so.

We bought a 34' 5th wheel toy hauler a month ago, moving up from a 24' travel trailer and the one thing I noticed was that my mileage is about the same when towing. I get 12 mpg towing both. The 24' had a slightly sloped front end and weighed in around 7200 lbs. The 5th wheel weighs in at 9500 and has a rounded fiberglass cap on the front. My guess is the 5th wheel takes advantage of the trucks aerodynamics where the travel trailer didn't because it was too far back to do so. Go figure...

 

[champspa]

towing my trailer and tractor 14000 , I get 11.

 

[Dean Upson]

Sound's about right to me. I usually get around 11 with my rig (see sig). If you drive over 65 the mileage takes a dive. I find 62 about the best speed with my rig.

[Casey Balvert]

Sure sounds about right. I got 11. 5 on a 2000 mile round trip a few months back pulling our fiver. Just about what I got with my 97 five speed with the same axle ratio.



Casey

 

[KenHokie]

Sounds about right. I just got 11. 8 MPG towing my 5500# boat a total of 240miles this past weekend. The round trip took me over a 7000' pass and a 8000' pass twice. Just dropped it out of OD and held 55-60 mph climbing them .

Towing Mileage

I had a 30 TT that weighed about 7,000 and I got about 9mpg pulling it. I sold it and got a 30' Jayco 5th wheel, weighs about 11,000 and I thought I would get worse mileage, but I pulled it 150 miles and drove another 100 miles in town and got 13. 6. I was pleasantly surprised and the truck pulled it much better than the TT. I stayed about 62 to 65 and 1700-1800 rpm. I have a friend who has a smaller 5th wheel and he pulled it on the same trip with his 96 chevy duramax duallie and got 8. 7 mpg.

 

[The patriot]

I have a hard time staying that speed. There always seems to be a rolling roadblock in front of me when I'm in the right lane. I call it "the idiot parade".

You go to the left lane, then they speed up.

I end up just staying out there and doing 75 just so that I dont have to deal with their B. S.
