Ehhhhh:monkey: I am jealous mine is 81 twin stick air ride and
I got it at around a million miles three years ago it keeps going and going.
Curious why you don't like them I know why no one like white western star:hmm3grin2orange:

Boss switched to Petes and K whoopers .......That old Mack was good in its day for drying your pants legs in winter...Loved the air window that opened on its own when it got below -10......Breath of fresh air.....

I used to drive an older RD with a 237. Wouldn't go above 55, but what a bullet proof motor that was.

You haven't driven a truck till you drive a DM (damn miserable) Mack...

The new 6.7L Cummins and the LMM are both piles compared to pre EGR engines, and that will NEVER change. My buddy has a 08 QC with the 6.7L and the 68RE, he's been getting 18mgp hand calculated in mixed driving, he picked up a full 1.5 mpg's after he hit 30K miles. Only thing he's had is 2 reflashes by the dealer. His parents own a 99 24V with 280K miles, I just replaced the 3rd lift pump in that truck (not too bad if you ask me). Thats a stock 2500 4x4 auto QC LB thats pulled a loaded 26' horse trailer twice a week since they bought it new. Weighs in around 12000-14000 lbs. They are on their second automatic in that truck, but of course they are older and don't abuse the thing. Their other son has a brand new 08 LMM Crew Cab 2500 GMC, he works for a local GMC/Pontiac dealer, and it does pull the trailer from time to time, and pulls it well. He's been getting 16mpg mixed driving, and he drives about the same as his brother. However, it does not like stopping that trailer. Granted, he needs to install a brake controller, but the 6.7L pulls and stops it just as well. Flip the exhaust brake on and the 6.7L tows that trailer leaps and bounds better than the GMC. The GMC has also had the computer reflashed a few times, and he's had a couple of injector issues, all replaced under warranty. Last I knew they replaced all of them under warranty. He's getting a little frustrated. The LMM will smoke the 6.7L down a straight line, by a few lengths actually, but thats if it's running right.

My other buddy owns a landscaping company. Drives a bright red F-450 SD with the 6.4L, with 35K miles he's on his 3rd set of turbo's, and that truck is stock. It has by far the best chassis of the three, but between turbo's, injectors, and head gaskets, that thing is nothing but a boat anchor.

As for my trucks, the 99 gets the best mileage, but for its size and power, the 97 has the best mix. I get 20-22 on the highway, and 18 around town.

Not trying to start a pissing match, just saying you are fairly local so why not let the trucks do the talking. To respond to some of your comments, The allison works so well in tow haul (engine braking) its overkill for an exhaust brake. Although with the new cummins its a nice option to compensate for the trannies short cummins. Your buddy had injector issues with a 08 lmm? Thats hard to believe, if you said lb7 it would be quite possible but with the 200k injector warranty its not much of a concern. Both my duramax's are modded and working daily with out any major work ever, They consistantly pull 30k+ and the LLY sees its fair share of the 1/4 mile and truck pulls almost always finishing ahead of comparible dodges and fords so IMHO GM's are better all around trucks, but to each there own.

Similar to the U model. Ever drive a B model with a quadraplex? Anywho, The coolest Mack so far ( besides the new Titan) is an RD800.

I understand Ford is developing an in-house built diesel,the Scorpion 6.7.Does anyone think that the manufactures in there quest for more HP and TQ,reliability is being sacrificed?I understand the pre Powerstroke fords while having relatively low HP and TQ by today standards were very reliable.What about the Mitsubishi FG truck,I've spoken to a couple of owners and they love them,again low HP and TQ,very reliable,7 yr. waranty,coupled to much lower gearing than U.S. light trucks.I had a 99 ford Powerstroke and now have an 05 Dodge/Cummins,like most things,they had good and bad about them.I also think with the price of diesel,the lower MPG new diesels are getting and the higher cost for the diesel option,people might be buying more gas pickups.For my needs,if I was going to buy a truck today,I would buy gas but we all have different needs.

That might be true in Fords case. 6.0 and 6.4 have bad records. Maybe the 6.7 will change that.

my lly is a nice truck, but i despise the fact that chev put the ifs in a hd truck though. my old 1980 gm with the danas rode like a dump truck, just like my buddies 08 dodge hemi does now. i think the overall package goes to chevy, ford is having too many trouble with their power plants(to me, even the tritons were junk), and i was never a fan of dodge trucks even though i love the cummins.

if you leave the truck stock, i doubt the dmax/allison will ever fail in the trucks life; the cummins probably wouldnt fail in our lifetime even if modded and is probably the best motor, and well ford is on its 3rd powerstroke in 10 years but the truck itself is nice.

personally, id like to see an allison 2000, in the chevy...

I would agree with most of that and I too would like a strait axle gm. Mostly just because there easier to lift and just look stouter. There are plenty of duramax equiped trucks running over 700hp and 1000lbs of torque on the stock GM cv's so I would not say there junk by any means they just need a couple add ons to the front end to handle 100-700hp over stock. My LLY has less then $500.00 in front end parts to beef it up to hold over 500rwhp and has seen plenty of boosted 4 wheel launches truck pulls, chain hooks, etc.. etc..

i dont think the weak point is the chevy is the ifs until you build the allison. i think without changes the allison is operating at about 80% its limit with the duramax, but build it and the next weak point is the ifs, fix that and the drive shafts probably will fail and on it goes....

As with any diesel truck the next weak point will eventually show its evil head when you start adding power to the drive train. The allison is built strong enough from the factory to hold some serious power but it is hindered by trying to shift nice and smooth and hold all the trq at the same time. A few simple mods to increase T/Q lock up and clutch apply pressures will enable a basically stock allison to hold up-ward of 600hp reliably. Yes the CV's have been known to break under extreme conditions but they are far from weak IMHO...

A FSP hauling 30K lbs? I want to see this load... Maybe pulling stuff from the field to the barn, but no way are you pulling 30K+ often and long. There is a guy on the DTR board who pulled something like 46K from Washington to Alaska (his steel building IIRC), but said he never hit over 45MPH.

Its not the problem of moving, its stopping.

And yes, my buddies LMM is giving him injector issues. The first time their diesel tech figured it was because of the computer going haywire, the second time he didn't have a clue why they went...

As far as the shortcomings of the 68RE, I have yet to find one, and if you look on all the boards, you'll be hard pressed to find any issues with them either. Another side note, take a look at the output shaft on a stock 68RE 4x4, then compare it to a 1000 4x4 output shaft, the Allison looks like it came off a Tonka truck. If you want to go farther, look at the connecting rods in the motor, the Cummins are twice the size of the Duramax, and we all know size really does matter.

I am local around here, and the Cummins trucks do dominate around here. BUT, I also hot-shot with my old uncle when he needs a second driver, and I can tell you we see a lot more Dodges and Fords on the east coast than we do GM's, and there is a reason.

One last question... If the Duramax is such a great motor, why is it you don't see them transplanted into Fords or Dodges? Because you sure do see plenty of GM's and Fords driving around with the B series motors, whether its the old 12V, or the newer CR trucks.

And Custom, the Allison can't hold 600HP even with a VB and TC upgrade. Actually I take that back, a 2WD can. The 4x4 will snap output shafts continuously with anything over 500HP in racing or heavy towing applications. Even daily driving will break them at that power if you try boosted launches or if you drive it like you stole it. NONE of the stock tranny's can hold over 450HP reliably with 4wd and a heavy right foot. Of course, any of them could hold 1000HP if you never use it...

There's 26k on the 04 LB7 with stock transmisson and front end. It has seen over 30k on many occasions and pulls it just fine, you are right about stopping being the biggest hurdle but with the trailer brakes ajusted and working properly it stops pretty good. This truck has been worked this hard since new and now has 113k on the clock and going strong. Also this truck has had the BANKS big hoss bundle on it for the last 90k on LVL-6 every day, granted the Banks does not put out crazy amounts of power its still putting out around 450 RWHP on a stock tranny and holding great thus far.
