Totally a non issue, no need to stress about it. Mine was one of the first that wouldn't reset after you filled it up, but since that has been taken care of it's been great. I put one jug in every 5000 miles or so ($13 for me or 1 cent per mile). Truck gets 20 mpg and has more power than any truck I've ever had, modified or not. I have had the truck since November of 2011 and am just now hitting 36k miles, I haven't come close to hitting the DEF tank with plenty of off road driving.

I've been a Bomber of diesel trucks since 99, these trucks are what we dreamed the factory would make back then, 400 horse, 20 mpg, and a drivetrain warranty to boot. Why worry about what might happen before you are even using the trucks?

 

Exactly Matt! the LML is a beast and the DEF is really not at all a big deal, as DEF is availible just about anywhere and it is fairly cheap per gallon that i have seen

 

It's false info like this that has people worrying about the new trucks.

DEF freezes, but you would never know it. The tank has a heater and takes care of it, there is no waiting for anything to thaw.

You don't empty it, you fill it up with DEF. If you put two jugs in you just do it when you change the oil, so no extra shop time there as it takes 5 minutes if you are slow.

Of course mileage, DEF has been around for long enough now that everyone can see the better mileage with the system as opposed to a DPF without DEF. DEF lets the engine program run with way less EGR, which means better power, better mileage, longer lasting engines.

Given the current emission restraints and ever increasing mod police at dealerships, DEF is a win/win for both teams.

 

Well theres already a hunk taken off the def tank so in this case theres a need for the skid plates. 3 trucks and 3 new skids on order.
I guess it will be a matter of time to see if the rest of my findings will come true or not Ill be sure to let you know!.

 

Well put Matt Def is a good thing , now will everybody stop worring about it.

 

whos worrying? i was just asking a question.. men ha!
btw thanks for straightening up my mistakes. I stand corrected, I meant that they need to be filled not drained.. my bad, we found the filler you put the def fluid into its under the hood. some older ones are beside the tank i read.
Also the issues with the freezing happened to someone else. they had to thaw it out in the garage.. different climates, different terrains, different situations. we dont all drive on prairie roads and highways. ever seen tough trucker... the logging truck issue, that would be our terrain. Oh yea ,, if they were so great the defs, why is there so many delete kits out there for them?

 

i know what you are up against jen. i worked in the oil and gas field for years. dragged with a dozer winch line you can tear off stuff.

 

Because there will always be someone who wants a loud truck with more power, which is perfectly fine. Why are they putting guards on instead of just deleting the system?

I would guess someone was out to get the def tank deliberately to prove a point in such a short time frame, but that's just me I'm suspicious of that kind of stuff.

 

I dont think there out to wreck anything.
There hauling a fuel trailer up some steep rugged hills to heli pad landings. This driver doesnt get involved with the mechanical side so it makes no difference to him..
I think they will wait till they break the trucks in first since it will delete the warrenty on them, but i think a lift kit might help that situation really. Its a shame because they are brand new trucks and need to be rethunk for this situation.
They have the big covered canopy on them too, which is really useless because they cant see anything behind them so next will be a backup display........The fleet manager at the time who ordered these trucks didnt do his homework.
Yes they are really pretty but they are not to be entered in a parade........
The cool thing i like is it has a engine brake in it, like the big rigs.. just hopefully they figure out how to use it.

 

All they have to do is press the button and drive like normal. The exhaust brake is variable depending on how hard you need to slow it down, again it's one of those things that when it's on you don't notice it really other than the truck slows down easier.

Any pics of what they're hauling and where?
