Towing a 67 Caravel with 96 F250 CrewCab 4x4 460cid Auto w/4.10 axle:

Solo - 11 - 12 mpg
Towing (55-65 mph) - 8.5 to 9.5
Towing (65-75 mph) - 7.5 to 8.5

An interesting thing happened on a trip west a couple of weeks ago. On the trip west from Ft Worth, TX to Silver City, NM burning mostly Chevron 86 octane fuel economy was just under 9 mpg. On the return trip I filled up in Silver City at a Diamond Shamrock with 86 octane and drove to Alamagordo, NM and filled up, mpg was 11.4, with a lot of mountain driving. Filled again with Diamond Shamrock and drove to Snyder, TX, checked the economy again - right about 11 mpg driving about 65 mph and this included making a long grade from Alamogordo to Cloudcroft. In Snyder I filled up at an Conoco and drove on to Fort Worth - the economy dropped right back to about 9 -9.5 mpg. I can't believe that a difference in fuel brands could make that much difference but that truck has never broken 10 mpg towing - however I've never burned Diamond Shamrock either. But on the Diamond Shamrock fuel I was hitting empty at 150-160 miles as opposed to the more typical 120 miles on the tank.

Another note - I tried to boost the fuel economy a little ( I was hoping for about 1-1.5 mpg) by adding the Banks Power Pack exhaust system - I gained nothing but a louder exhaust. Towing power might be a little better when accelerating hard to merge into traffic but otherwise there's not much difference in the power band that I'm towing at which is 1800 - 2500 rpm. My wallet on the other hand is much lighter.

Last week I drove to Alexandria Minnesota for a business trip. Coincidentally, I was getting the trailer out the weekend before to de-winterize. So I thought why not take it with me .

Anyway, I averaged 14.7 towing our 28' CCD for the entire trip of 1691 miles.

2005 Ford PSD CC LB 4x2 Lariat.

Staying in the trailer was MUCH better than a motel.

I stayed at Lake Carlos State Park and had the place to myself.

1st Trip

On our tow home from picking up the Caravel we got about 12.8 mpg DIESEL. I will be watching closely on the trip next week and will reduce my speed to just over 60mph as a caution for the axle and we will be loaded a little more.

I just got back home from a 3 month, 4100 mile trip in my '72 Ambassador, loaded for living. Plus I had about 1000 lbs in the back of my '01 f250 Crew, 7.3 Diesel, auto, 3.73 rear. The trip was from Sedona, AZ, to Tucson, to Placerville, CA, back to Sedona, then on home to Cleveland, OH. Lots of mountains........ I averaged 13 MPG towing the trailer. On the Cleveland to Sedona leg, without the trailer, but with 1500 lbs in the back, it was about 16 mpg. Just driving around, with nothing in back or behind, I get about 16/19 mpg. Stay out of northern CA in the winter.

I might add that I keep it at 65 with the trailer behind me. Posted speed limit +10% without. The truck doesn't seem to know it has anything behind it.

Good idea for a thread! Where we are in CA we are paying $3.30 for reg. unleaded. Pulling a 2001 Bambi up the Ca. coast this past weekend with a 2000 Suburban, 4x4, 5.3 ltr. Vortec we got 13.71 mpg. If/when gas gets to $5.00 a gallon I may have to convince my wife to let me put a hitch on her Subaru Forester!

My last 5 tank fulls while towing my '86 25' Sovereign were 11.11, 11.36, 10.01, 10.79 and 10.33 mpg with a '01 Chevy 2500hd, 8.1 litre engine, Allison 5 sp. auto trans, 3.73 rear end ratio, Amsoil dual bypass filtration system running Amsoil 5W-30, Amsoil Severe Gear rear dif lube and Amsoil TorqueDrive syn. trans fluid. Interestingly enough, my last trip solo on the interstate netted 15.17 mpg which was one of my highest so far. I'm usually pretty steady around 14.7-14.9 mpg solo on interstate at 68-70 mph.

We get 12-14 mpg towing a 2005 AS 25 Safari LS with a 287 V8 dodge 2005 dakota.
I am excited to try out my FFI fuel caplets towing my AS. I've already increased my milage from 15.1 mpg to 17.8 mpg on the local street driving, and 18.3 to 19 on the highway. I expect I should get about 15-16 towing the AS with the fuel caplets. I know 15-16 mpg towing may not sound like alot but it's far batter then getting 10-12 mpg.

Anyway, didn't mean to lay a sales pitch on you guys.

Take care,

Towing a 1976 Sovereign 31'
15.0 towing from Albuquerque to Farmington at 65 mph
13.3 towing from Farmington to Moab at 65-70 mph
14.5 from Moab to Farmington through Cortez and Mancos, CO at 55-65 mph

It appears that just a little throttle discipline will generate a 9% improvement in fuel economy. I seem to do best when I release cruise control on the uphill mountain grades and reduce speed to allow it to stay in 4th or 5th gear.

11.6mpg pulling a train..

Took the 99 Safari 23' on a nine day get-a-way to Las Vagas.. Found the new Bass Pro shop at the Silverton Casino, (pulled in looking for the campground they used to have... it's no more...seems it wasn't cost effective.) Anyhow, bought a 17' boat w/115 Merc Optimax ...(can't resist a sale, and I needed a new boat).. took all my toys out to the RV village at Lake Meade. (one at a time).. found a welding shop that put a receiver hitch on the back frame of the Airstream.. trained it home to Wyoming.. pulled great..just watch your swings. We got 13 to 14 mpg with the 06 3500 Dodge CTD automatic, with tow/haul engaged.. pulling the AS and dropped to 11.5 to 11.8 with the boat behind.. This is our second summer with the trailer, no problems to report... HTH Les
