They are go anywhere, last forever trucks.


I think the 03 model year can also be included in this category. Also, I believe there was a switch in mid-year 1999, to the 7.3 engine version that so many like. So, if you see one that is a 99.5, that is considered one of the good ones.

the 04-06 year has the 6.0 liter PSD, which some claim is a POS. I dont know. The 7.3 liter has a better reputation, anyway.

Mines a 2000. I use a programmer, but I understand there are better ones out their. In about 140,000 miles of use, I've had to replace the water pump at 100k which, I am told, is typical of engines that used the FW-16 coolant additive to alleviate cavitation. Now, I run Final Charge in it, so hopefully that will take care of that.

I have done some other mods. I put in an aftermarket accumulator body in the tranny to stiffen shifts and it's made with better components. little over 100.00, self installed.

I also replaced my stock Ford torque converter with a triple disc model, for safety's sake. The stock ones from 99.5-03 were single disc which led to lots of slipping under loads, which led to lots of heat, which led to a fair number of failed trannies. Hence, the reason someone mentions the desire for the Allison tranny. I found the TC from a Ford dealer on line for around 300.00

That's it except I run synthetic tranny fluid and I found a way to install a 19.95 filter mount and put it inline with my tranny hoses. On the 2000 (and possibly other years), you have two sections of rubber hoses where the tranny lines go to and from the tranny cooler system in the radiator complex. I just disconnected the return line to the tranny, connected it to one side of the filter and purchased a length of hosing to complete the connection back to the tranny. I mounted this inside the passenger side wheel well with an "envelope" of galvanized mesh around it for protection. Now, I have filtration down to much smaller particles than the internal screen and I never have to mess with cleaning that screen when changing out my fluid. Slightly larger fluid capacity, too. The mount is a simple Derale 13005 and I use a basic PH8A-FL1A-51515 filter on it.

I recently got 17 mpg on a roadtrip doing 70-75 with about 500 lbs of cargo, not counting about 400 lbs of passenger. On the same trip I got over 18 doing 60-65. 3.73 rear axle, stock tire size, AT, 4wd, single rear wheels.

Perhaps you're right Hook.

However I comfortably pull a 3,500 Ib caravan with a 2.2 litre HDI diesel.

Therefore I am wondering if smaller, better tuned, more economic engines are the way forward, better fuel economy and better for the environment!

I wonder if fuel prices in the US reached the same high levels that they are in Europe (particularly in the UK) would peoples attitudes change?


As you were.


What is this engine mated to?

For many of us, the decision to go with vehicles with such large engines is, in part, because of the relative strength of the tranny associated with the package.

A 2.2l diesel engine might well pull some significant loads. But is the tranny built for that or is the whole drivetrain built for economy from a diesel? That's a big consideration when you're pulling 8k lbs in 100 degree heat.

It's mated to a standard 5 speed manual gearbox, not so many people drive auto over here.

A good Test for Information might be if someone could contact the "Hot-Shot Haulers" and find what they are using. Here in the Texas Area I have noticed mostly Ford Duallys but when I got over in Tenn. I noticed lots of Dodge Duallys.
It would be interesting to get their Imput.

It's not much of a consideration any more. The truck has done most all the heavy towing it's going to do. The trailer will eventually be moved three blocks over on to our lot. The drive to the ramp is about 3 miles at about 30 mph, so not much heat can develop on those runs.

We will be taking the truck and camper back to the States from around July 15-October 1 each year. That will be it's only heavy work now. Camper is about 2500 lbs, loaded. May tow the Wrangler, not sure.

Those temperatures dont seem to exist over here, though. Have seen 96 once, generally everything is in the low 90s for Aug-Sept.

Did I say Ford E350? I meant Cadillac E350 with some sort of STAR engine. Looked kinda like that Johnny Cash car he sang about.:lol:

My 1997 Ford Powerstroke Diesel is a Navistar engine. Not sure if they are still the supplier for diesels to Ford now though.

"Northstar" is the 32 valve V8 used in some Caddies.

IMHO, have spent 2 Mulege trips with a a 92 chevy 6.5 turbo diesel, auto,4x4, 4.10 gears pulling a 6K trailer without a bobble then day trips over to Mag bay camping and fishing. Rock solid performance with 14mpg with trailer and 17-19 with just camping gear and tin boat on top. Gave that rig to youngest son for his business. Bought 2004.5 GMC duramax/allison 4x4, 3.73 gears used with 67K. avg 12.5 mpg on last years 6K trip to the south and over the rockies with 8K trailer in tow and tinboat on top. with boat and camping gear in shell it runs 16-18 mpg.
Very comfortable quadcab 1 ton . did install prefilter for fuel and synthetic fluid in trans and front & rear ends & transfer case, edge chip for power and mileage although don't know why as it goes much faster than i do. A bit clumsy off road with the long wheelbase but am learning to get around with it. Do YOUR shopping, there are some great deals out their right now with $$ being tight.
