Aux fuel tank w/ramboxes

[Omarf4]

Looking for aux fuel tank setup for a 2500 with ramboxes and having a hard time sourcing anything in the 30 to 40 gallon capacity. The bed dimensions with ramboxes have a max width of 50”. The rds aux fuel tank (33 gallons) is 50 inches but that doesn’t include the drain outlet attachment for gravity feed.

Anyone know of any options to meet the following:
- must fit below bed cover (height needs to be 20” max)
- width at 48” or less
- gravity feed
- 30 gallons minimum capacity

Any help would be appreciated......

We use it other than to fill truck but also to fill large light towers.

Thanks. Looks sweet. Unfortunately won’t fit under the bed cover for me. I need the bed cover to secure other items (tools). Search continues.......
