I can't seem to find a Chevy Suburban 2500 with a Duramax engine. Anyone know of one for sale? I'm looking at buying a gas engine 2500 with the 8.1L v8 engine. I would rather have the diesel.

I drove a 7.3L 2002 Excursion last night (diesel). It's too much for what I need. I'm looking at towing an Overlander which will weigh somewhere between 6 and 7k lbs. loaded.

Chevy doesn't offer the Duramax in the Suburban. I'm perfectly happy with my '01 2500hd with 8.1 and Allison transmission. I get 14.6-15 on the highway, 10 in town with AC on and 10-12 mpg while towing my '86 25' Sovereign.

The million dollar question that all Suburban owners have been asking for about 3 years now.

Such a beast does not exist......yet, or at least in public.

What About Dodge?

Okay guys, time to throw my hat in the ring here. Granted, Dodge doesn't make a vehicle comparable to Ford or GM's Ex and Sub, however I am absolutely in love with my new 2005 Ram 2500HD CTD. I've had it for 5,600 miles now, and the best mileage I've gotten with it has been 21.9MPG Hwy and 17MPG city. The one thing I'm not crazy about is the 48RE tranny....basically a Torqueflite 727 with overdrive on steroids. Upon deceleration, the transmission has this feature which allows the driveshaft to spin faster, so that the motor doesn't overtorque and blow. The drawback is that you can't run a factory exhaust brake....only on the manual tranny models can you use the exhaust brake. This overtorque unlock feature has been reprogrammed in the ECM for the 2006 automatic models, making it now possible to add an exhaust brake. I'm going to ask the dealer if my ECM can be reprogrammed in mine. Now, if only Dodge could get ahold of the Allison tranny for its trucks! By the way, I am a die-hard GM guy, but I got a deal on my Dodge that was $12,000 less than the Sierra 2500HD D/A.

I've heard the same thing....only difference that I heard is that they won't have an Allision tranny, but a modified 4L80E. Now don't get me wrong, if this is true, which I'm not saying it is or isn't, the 4L80E is a great tranny, but I would be skeptical given GMs track record for converting things to suit their needs (IE early 80s diesels) that the 4L80E would be able to take the power off a robust diesel.

Of course the rumor mill I subscribe to could be way off and an Allision trans could be in the works....all I know is, I myself would love to see a diesel back in the 'ol Burb, but would be uneasy that first year or two if they did in fact have the 4L80E behind it, modified or not.

blue oval over the ram with a bowtie!!!!

hi guys

did the full shopping exercise in april...drove 'em all....several times, read everything from consumer reports and crash rating to all the trade truck magazines.....yeeeee haaaaaaaa!

opted for the ford 4x4 sd f-250 sc lb psd, with tc package....don't ya just love all of them initials.....

first the gm is an oooooooooooold design. yes it has indy front suspension but the nicest/most unique item....the q steer, was not to be found and is now history...the allison tranny is an alli in name only...it is not the allison found in the big trucks...lots of info on this on the bowtie boards....i know it's still nice but it ain't a real allison kids.....

the ram is cutting edge style but build and drivetrain still aren't ready for prime time.....

the ford is a tow rig.....like porky has said, they got the mirrors right....and that's important. the powerstroke is a beast even at 6l and at 15kmiles in the last 4 months it's doin' fine on mpg......and actually the tranny is a 6 speed but uses 2 different 5 speed programs depending on drivetrain (1,2,3,4,6 or 1,2,3,5,6) as i understand it...

and the power stroke board on yahoo is the best auto tech site i have ever used.......thank you mr. ledger for answering questions like a real master mechanic....his web site (diesel dog) also is a great tech site with all of the recall/tuning and service info anyone could want......and faster than the dealers have it....

anyway back to the truck.....

the tc package is the deal maker..... with a top notch brake controller working from the master cylinder and tranny tow/haul programing and real gear holding on downhills and those mirrors.....well it's exactly what anyone towing a load needs and is "factory" equipment.....and a modest priced option package as well.

until the others design/package a towing setup for their midsize trucks....ford really has'em.....i am really amazed that gm and dodge didn't get'er done for the 06 models....

i know airsteams and gms go together like pb and j but the ford is real meat and potatoes for towing (how da ya like all them metaphors)

by the way this is my first american built ride in over 30 years....so i have no loyalty for any of the brands......till now.

cheers

2airishuman,


Very well written, but I'm not sure I'm tracking with what you wrote. My father-in-law had a new 2001 2500HD with the 8.1L gas engine and the Allison 5-speed....that tranny is darn near bulletproof. He towed my 1972 Suburban (402cid, TH400 and one heavy mutha) on a flatbed trailer, from Colorado Springs to Monterey, CA. He averaged 75MPH up and downhill. The truck never knew the Suburban was behind it.

I took a look at the Fords for a really long time. I'll admit, that inline brake controller is a great idea, but what I don't like is the fact that....well, that it's built in. I don't know if it's that I'm stuck in my ways, but I like the idea of being able to take my controller out of one truck and plugging it into my other truck (moot point now, since I only have one vehicle). Plus, what happens when (and I do mean when) the thing decides to stop working, AND your truck is out of warranty? How much is the replacement controller going to cost? These are questions which made me resist buying Ford.

And finally we get to Dodge. I'm not sure what you mean by "build and drivetrain aren't ready for primetime". That Cummins Turbo Diesel of mine has the most torque and horsepower...350HP and 610lb/ft, and I'm pretty sure that the body will fall apart, before the motor will. Okay, I'll concede that the tranny leaves a bit to be desired, but if what the techs at my dealership tell me is true, that 48RE will have a long life of towing, provided I take care of it, per manufacturer's recommendations.

In my travels across the U.S. (and I've done it more than I care to remember for the Army), I've seen Fords, GM's and Dodges towing, but I couldn't say for sure that I've seen one more than the other. I think what it comes down to is personal preference. Although my personal preference is GM, the reliability of the Dodge, coupled with the price tag and other bennies I got with the truck, ultimately made my decision for me. I ask you this, if you had your choice between the three trucks, and the Ford was $47,000, the GMC Sierra was $43,500 and the Dodge was $35,000, and you had pretty much the same options in each vehicle, which would you choose? The choice was obvious for me.

FYI: My 05 PS Excursion with tow package went for $40K a month ago ... the mirrors might be worth $5K over the Dodge.

My take is that Dodge, though great new fresh sheet metal, but has very poor transmissions. A lot of smoke and mirrors. I mean there is a reason Dodge is #3. A number of folks here at one point talked about their trans eating itself.

In the end, if you stick with Ford or GM, you won't be sorry. My pref is and always has been GM. Not that the folks at GM are angels, they clearly are not, but regardless of dated equipment, things like 350, Duramax, posi....all GM....like Lee Iacocca said, "Lead follow or get out of the way". Clearly, GM and Ford care about what's under the sheet metal and to me, that's what counts, not the fluffy stuff....

Ford, Chevy Dodge

I had a talk earlier this year with Campcollector about this very subject and he came up with a great idea. A Cummings engine attached to an Allison trany in a Ford chassis. Not a bad idea in my book.
Well guess what I heard the other day? Dodge just bought the rights to the Allison trany used in the Duramax, a 5 speed Allison matched to the Cummings engine coming in late 2006.
Chevy has outfitted the new Duramax with a newer 6 speed Allison.
Still in the Dodge body but we're getting there.

Gary,


One thing I found out from one of the techs at my dealership is that Dodge has always owned a portion of Allison, just not the right portion allowing them to use the trannys.

Smoke and mirrors, though Twinkie, I disagree. From what the techs say, Dodge re-engineered the 48RE to withstand the torque from the Cummins. I'll let you know, when I put it through its paces. I've got the 7yr/100,000mile bumper to bumper warranty, so believe me if there's a chance that it'll go, I'll make it go while it's under warranty! By the way, I have the "Mickey Mouse" tow mirrors, and they ROCK!

I will be pulling a 31' sovereign along with a wife, two kids, a 50# dog and 2000# of cargo distrbuted between the truck and trailer.

I am not soliciting Ford or Chevy bashing, simply an honest education.

Thanks

You will be many dollars ahead if you buy a camper shell for your current truck.

You'd be disappointed with the performance of any current gas Suburban (compared to a diesel) unless it has the 8.1L. The GM 6.0L is a good engine but my 6.0L PSD has more torque at 1,000 RPM than a GM 6.0 gas V8 will ever have.

The 5-speed Ford automatic is a great transmission. Prior to this truck I would not own a Ford diesel with an automatic. I have no experience with the Allison used in the GM trucks.

The 6.0L PSD earned it's reputation as a fuel hog because of how much power it produces and how easy it is to access the power. My best mileage so far (my truck has 13,500 miles on it) has been 17.8 empty and a worst of 10.0 towing. I get 13.5-14 MPG towing on level ground @ 60 MPH and manage 12.5-13 while towing in the mountains @ 65 MPH.

there is always a little hyperbola when folks brag on their trucks....

hi stingrayl32 and others

while i hadn't owned a big 3 vehicle since my '60s nova, i was pleasantly surprised by how well they all are doing with the trucks. this is partly because so many folks buy these trucks and partly because the profit margin is high (very close to the suvs) and MAINLY because the big three are now mostly 'assembly plants' as apposed to manufacturers.....by this i mean they contract for the big pieces from others with some "brand" loyalty and reputation for quality; and then they do the assembly and sheet metal.....so it they have great engines and trannies and axles and so on....they can build a pretty good truck....

i did't say the tranny in the gms wasn't durable and well made; i've heard lots of great reports of just how good it is........just that it's not an allison from the same plants and bits as the real allisons.....sort of like schwinn bikes made now are schwinn in name only, from asia and so on.

why doesn't gm call it an izuzu diesel with an allison tranny. izuzu has been makin diesels a long time and has a good rep worldwide......? it's likely because izuzu doesn't sound as american or have the rep of allison stateside. it's just funny to me how the big makers utilize selectively the subcontractors brands in their products....doubt we will ever see a new "ford firestone" but we do have a new "ford 500"....

yep when the controller fails we will have service issues, but ford has sold more of these controllers wrapped in a truck than all the other brake controller makers combined. so service for these or upgrades will be readily available and not too pricey....in fact there is already a factory kit to retro the controller in 04s or 05 that didn't have it originally. i suspect there will even be aftermarket 'improvements' by vendors who realize how many of these gadgets ford has sold....

as for the dodge, not being ready for primetime was my way of saying the body, interior and other obvious user interfaces, just seem of lesser quality and fit.....some parts are very nice like the shinny bug deflector and wheels, but most of the interior trim, fabric and body panels just seem to be a notch below the gm/fords.

as for what i'd buy based on price.....my fully decked out (49k) ford was closer to 40k....they were doin' the employee pricing way back...you just had to negotiate for it.....so the gap between the ford and dodge is narrowed, especially since the mirrors and brake controller and so so still have to be added to the dodge...

but THE truck model that would be great for us trailer pullers is the dodge "contractors" model...it's the big diesel with a built in 12kilowatt generator and an assortment of plugs.....pretty cool.

now if they'd just get some big mirrors and the towcommand bits...

cheers
