Auxiliary fuel tank

[Luke]

I have a 2021 desiel 2500 and want to get an auxiliary fuel tank to increase my range. We pull a 5th wheel and have the factory tri fold tonneau cover that I would want to able to cover it. Looking for a 40 to 50 gallon rank.
Does anyone have a recommendation

Transfer flow. Titan. Local welding shop. Pick your poison. They all make what your after

Thanks for the reply. Titan are a little high priced, but they appear to be everything that I am looking for

I've also been hunting for an Aux fuel tank, mainly for when I tow my travel trailer. I've considered the titan 52 gallon factory replacement tank, but i'm afraid to give the dealer any extra excuses should my CP4 fail, it's also a lot of money for only an extra 20 gallons... I was considering an in bed tank but everything is permanent and I don't want to sacrifice any of my short bed space when i'm not towing. I was hoping i could find something sorta modular I could quickly install for towing trips and remove for daily driving, but no such animal seems to exist.

Closest thing i found was this guy that would be easily removable and still fit under my tonneau cover:

Still have to pull over to refuel, but it's got a pretty good $$$ to gallon ratio compared to the titan stuff and can be strapped in and wired to an Auxiliary power plug in the bed. So I figure while towing the factory fuel tank seems to run dry around the same time my bladder gets full so stopping off quick at a rest stop to relieve myself and refill the factory tank wouldn't be a big deal and would help reduce those critical fuel stops where regardless what the exit or fuel station looks like, you gotta take it.

Luke I have a 2020 Dodge Ram 3500 6,7 converted to R/H drive Australia. I had the same problem and had an Australian Company fit a 200ltr Tank
from USA. It fitted with no adjustments and they even recalibrated the mile to empty on Computer Dial . Allan

Have you checked out S&B or Aero Fuel Tanks in SoCal? I think aero only does long bed for the current trucks.
