2017 GMC/Chevy DEF tank!

Personally, I'd rather see my truck use whatever amount of DEF is needed to keep the exhaust within spec's than EGR. Those are the only two viable options when it comes to reducing nitrogen oxide emissions in Diesel exhaust; either reduce the combustion temperature in the cylinders with EGR or use a SCR after-treatment.

:):)

The problem using too much def will cause the exhaust to clog up over time

Out west, many of the boon docking sites and off-road staging areas are a challenge to typical RV's which is one reason I stayed with a truck camper on a 4wd truck. I also don't plan to take my truck off the beaten path beyond a logging or fire road, but even some of those can get rough. If you ever camp in primitive sites, you will see they are not kind to low hung vehicles that cannot turn sharply. Like you, the tough terrain is explored with dedicated off-road vehicles we bring with us, but you have to get to the camp first.

Ive been involved in rock crawling with Jeeps, gave it up, this truck is not intended for that.

BTW, if I want to off road now I have a ATV for that.

As for the 2017 GMC im sure it is a very nice truck just like the other 2 brands, they all have their down falls you just have to pick which one you want to live with.

Off roading....I did that once in my truck, trying to turn around on a back road my front tires touched the sand. That's all the off roading this tow queen will ever see as long as I am driving her.

My concern with the gm def tank was more so if some road debris kicks up and hits it, yes I know that can happen to any vehicle.

There are many variables to off roading! I took mine into the back year (and got stuck in the clay). I have driven in farm fields, which is off road. I have driven Michigan UP fire roads, which is really more off road than road. I have been on sand dunes, which is off road. I have not driven on rocky ocean beaches (because I have seen video of what happens when the tide comes in).

So we all have our experiences, and we all pick out things that we can live with. As for the 2017 GM 3500HD, I can say that it is fantastic for me.

I find it interesting that the first time I had to add DEF to my truck was around 1000 miles (new). Took me by surprise and started wondering what I just got myself into purchasing something like this. Yes, we were on the road with trailer in tow.

Next fill up was about 3000 miles after that, then about 4000 after that, and now it's filled with every oil change. My truck is now 30,000 miles. But yes, I have filled mine on-the-road a few times too. When traveling, I always bring along a jug of WallMart DEF.

Even with step bars you are not going off road in a GM/Chevy Duramax!

If I paid $65k for a truck, I wouldn't be "offroading" it. I have a Jeep for that.

$65,000.00 one ton dually. I have no plans to take it off road. That's why they make Jeeps. Hasn't been a problem in any way in the two years I've owned the truck. I like the fact that the DEF is under the hood. When is the last time you heard of someone pouring DEF into the fuel tank on a GM product? It's not like you have to add DEF every week..

Ditto.

Also, the DEF tank has been in the same location since he 2011 model year.

It might be a different size/design on the 2017 - it's hard to tell from the angle and lighting of the photo in the first post.

Honest question...Can you fill up the DEF tank at truck stops without having to move the truck after filling up with diesel? I know the DEF pumps can be hard to pull out and I've never tested how long the hose is.

I've never had to fill mine up while on the road. I only fill it when I get an oil change. I agree it's not in a great place, but I like that it is hard to spill DEF on my paint.

X2, fill mine up during the oil change and have never had to add out on the road.

Yes, I do tow quite a bit all summer long.

I used to use the 2.5 gallon jugs until I tried the truck stops. To me it's easier, cheaper, and very convenient with no spills and no box to dispose of.

im not worried about the amount being used just assumed that since the engine is revving a little more it is consuming more def.
