LM2 fuel tank question.

[Rubyralph]

Has anyone that owns a 2020/2021 3.0 Duramax LM2 pickup installed a in-bed auxiliary fuel tank to extend towing range?

I'm interested in the T____n fuel tanks but they don't offer a kit for the LM2 as yet.

Thanks Ralph

As far as I know nobody offers an auxiliary set-up yet..

 

I did speak with one of them last fall about an in-frame tank and they indicated they were expecting to have something first of the year -- and of course nothing yet....

 

For now it looks like a transfer tank (as opposed to auxiliary in-bed or an in-frame) is the only option if extra fuel is desired. 

 

With tank ranges of +/-600 miles I've got to admit I'm less interested/concerned than  was.

Previous truck was 6.6 dmax (2011-2019 were 36 gallon) and gave the same range when travelling (and not towing)

I was looking for the same, minus the DM part. I have the 6.2 and I was hoping to find something to get me trough the 600 mile barrier due to my work and home being 579 miles apart.

Transferflow has some of the better in bed options out there. I went a cheaper route and wished I would have gone TF.

Thanks. Looks like they don't have anything for my 1500, unfortunately. I wish they had something like the 45 gallon tank they have for the raptors.

I wonder if this one will fit in a 1500 bed?

Thanks guys for your help...I have contacted both Titan and TransferFlow  through their website's contact links.

Both haven't responded yet, I don't want to spend time and money to find out I may have installation or operational issues ie: the emission system CEL that my truck seems to have enough of on it's own.

So I'm still looking for someone who has installed a auxiary diesel LM2 tank and what they have had for results in our T1 1500 series trucks. 

Thanks again, Ralph

What's your emission CEL issue story?

I have had DEF related CEL(s) since new, I now have ~4K miles and have had at least 4 CEL at the dealership, they just replaced the following parts:
84914535 tank, 84620945 harness, 84714454 controller, and 3 1/2 gallons of DEF fluid. My issues began when new from the factory when the same dealer said that the DEF pump connector pins were wired wrong!
I hope this resolves my DEF problems as I plan on some long road trips this summer and I really want to enjoy the truck but I'm losing all hope of it being repaired correctly, which is a shame because I love the drivetrain of this truck.
