Aux water or fuel tank?

[RAM5500 CAMPERTHING]

I'm still really hoping I can find the OEM subtank, not for any clearance issues, just so I can a) still carry a spare as I sometimes do and b) also thinking about putting either air tank or winch back there too.

Just keep in mind, it is A LOT of work for small gain, it is a fairly time intensive mod. When its all said and done you will probably be within $200-300+/- of the big daddy. The prices of those OEM Subtanks has SKYROCKETED in the last few years!

Good points though about keeping the spare though!
