Miles per gallon thread.

also MPG

We tow a 1997 24D with a 2002 V10 Excursion (270K). At 60 the excursion gets 15.3 and towing the Hi-Lo at 60 we get 12.3. We haven't had it long enough to know what the mileage is at 70. When we get back from Alaska I'll post the mileage info.
 
I guess I've been lucky when towing the "Beast" (3389b). I have a 2012 F-150 super crew fwd. V8 with 6 spd. auto trans and a fiberglass bed cover. Our Hi-Lo weighs in at around 7000 pounds in travel mode. I make sure all the tires are inflated to 50 lbs. When we get out on the highway I run up to 65 mph., punch the cruise control with od on and we get 13 to 15 mpg. We have a 20 ft. enclosed car hauler trailer and even with the V nose we only get around 9.5 mpg. Thank you Hi-lo.

Bear :D
 
1987 F250 6.9l diesel 2wd manual transmission with slightly oversized tires:

City - 17mpg

Highway - 20+ mpg

Towing 1995 HiLo 24' Funmaker (no overdrive) - 12.5mpg
 
07 Tacoma Prerunner double cab short bed V6 auto. 2404 HiLo, 300#motorcycle in bed on a trip from McGregor, Ia to Dover, AR and return with about 40 miles with out the camper, driving mostly 60 mph=14.01 mpg. I was happy with the trucks performance in the Ozark mtns. Coasted down the hills and used the momentum and a steady throttle to gain the top of the next hill, losing about 15 mph in the process but usually only down shifted to fourth. Pretty effortlessly pulled the load in 5th on the level with an occasional unlocking of the torque converter.

I'll bet some real altitude would make the 4.0 wheeze!
 
14 mpg

we have an 01 excursion diesel. at 70 we get 15-16. with 21 footer we get 13-14. so not much loss there. we dont have an WD hitch yet and someone said it may help. i am also adding a rear hitch for a boat so when i add all the goodies i will re-check it and post the results.

boat is light, jon boat with a jet motor:D

the mileage is one reason we got the hi-lo...cant beat the wind! with my dads 32 foot jayco we get 8-12mpg depending on hills and speed.
 
We have finally returned from 13,000 miles of touring Alaska, Canada, and Pacific Northwest. Beautiful country, but I don't want to see another wheat field in Canada for awhile. Corn belt farmers may think they feed the world, but I'll tell you this: Canada's wheat will give them at least a run for their money. I was glad to finally see a pine tree somewhere around Calgary.
Now, on to the mileage. We kept very, very close records along the way and the very total at the end was 10.8 MPG overall. We were towing a 24 Classic with about 800 pounds of gear and four adults, Ford Excursion V-10 and generally ran about 68. The Ford just passed 300K.....it's for sale....any takers?
 
Greg, we brought along two EXTRA spares mounted on top of the TV and we had NO flats, NO blowouts, and not even one low tire. We started with four new tires and had one with a little uneven wear. The tires could take one more trip, but no more than that. And yes, we has screws coming loose all the time. This is not I-80 in Canada and Alaska. The trailer performed without a hitch. And I might add, we sold it two days after we got home. We only had a chance to clean the inside, not the outside. We are headed towards a 36 foot 5th wheel toy hauler now.
 
Jim, since you are looking for a large fifth wheel, I gather that four people in a 24-foot Hi-Lo on a long trip to Alaska was a little too close and personal. Also, when you mentioned there was a lot of loose screws on this trip. Was that primarily on the tow vehicle or the Hi-Lo? The RVers I've spoken to who have made the trip say it was a trip of a lifetime, and everyone should do it at least once.

Glad you had a great trip! Linda and I did a six week Alaska and Canada trip in 2012, but since we didn't have to drive as far to get to the borders, our trip was only 9700 miles and we were pulling a 1999 21T. I don't remember that many wheat fields in Canada ( I did all the driving), but what caught my eye were all the canola fields, which were beautiful. We hope to get back to Alberta next year...did not get to spend time in Banff National Park.

Well, I bet if you hadn't taken any spares you would have had two blowouts! Regarding screws, I bought some Loc-Tite and plan on putting them on all the exterior screws (all 4 million of them).

Glad you made it back safely and enjoy your new rig!
 
2006 Toyota tundra regular cab long bed. 2wd, V8 and 5 speed automatic. Completely stock with 3.92:1 gear ratio. I had approx. 500 pounds of motorcycle and fuel in the bed.
2203T fully loaded with full freshwater tank and food/beverages/supplies for 1 person on a 3 day weekend.
338 miles traveled round trip with 1 decent sized hill (Whitewater grade on the 10 freeway near Palm Springs). The conditions were pretty optimal with little traffic and almost zero headwind so I think this is a best case scenario. I traveled a steady 60mph with street pressure (35PSI) in the both truck and trailer tires. Fantastic milage!
14.9MPG.
Fireball, I sent you a private message.:)
 
My rig listing is below. Trailer load was 5100 lbs and over a 2700 towing mi trip, we averaged 13 mpg. Mainly flat to rolling, some mountains, speeds 60-70, rpms 1500-2000 (except mountains, 2500), and stock tires aired up to 50 psig. We did some back road stretches at 55, and the mileage improved to 14. This was the first trip with the Tundra as TV, and I was pleased with the mileage. Compared to my old TV (Explorer 4.6L V8), we ran faster on the freeways and mountains and got better mileage.
Actually, I think it makes more sense to figure how much extra fuel it takes to tow 100 miles. The Tundra gets 18.4 mpg by itself, so towing the HiLo took 2.25 gallons more every 100 miles. I remember seeing some brochure where the HiLo claim was an extra gallon per 100 miles.
 
I believe the HiLo figure was the comparison of mileage of towing a HiLo vs. a conventional travel of comparable size. That was mainly to show what the difference in wind resistance does.
 
I've been wondering what our mileage when towing is so on our recent trip I actually kept a record. Not towing, my Tahoe gets 16 mpg. On our 1,300 mile trip, we averaged 13 mpg. Considering the high winds and high elevations we traveled to, I was happy with it! :)
 
Our 2703 Tow Lite grosses around 5000# loaded. Our 6.5 Turbo Diesel gets about 14 mpg +/- on the Interstate at 60 mph. Every time it has been checked it was near the same mileage. Not too bad.

When we did our trip last year to Utah, Colorado, New Mexico and Texas (3200 miles) with our 2705T we averaged about 12 mpg with the 2005 Tundra, so now I guess that wasn't too bad, but when we did our tips to Alaska and Canada ((9719 miles) with our 2199T our mileage was about 14 mpg.:)

Garry, that's because you were further North and there is less gravity up there! :D
