Semi-necro-bump (body is still warm, perhaps? ) as I figured out a better alternative for those who want CNG bi-fuel capability in a truck that does truck-stuff (payload + towing capacity) much more respectably:



There exist multiple companies doing Ford-approved CNG dedicated and bi-fuel conversions on Ford Super Duty trucks. The plus, relative to the Ram in the OP, is that said conversion companies will convert any variety of (6.2L gas-prior-to-conversion) F-250 or F-350 you throw at them.

Regular cab SRW F-250 with tall highway gears? Sure. Crew cab long bed DRW F-350 with 4.30 gears? No problem.

Said F-350, set up as above, would have a GCWR of 22k, a GVWR of 14k, and would weigh around 7k itself. Even accounting for a few hundred pounds of CNG conversion detritus + tanks (Westport quotes 248 lbs for their whole system, for instance) that'd still leave plenty of capability in store: Ignoring the CNG system's weight such a vehicle would have towing capacity of 15k and a payload inclusive of passengers of around 7k.

Not bad.

What's more, BAF Technologies, one of the many CNG upfitters out there, will set up such a truck with 10 GGE of CNG under the bed, where such tanks should logically live. (If you want more they'll stick an additional 20 GGE in the front of the bed, a la Ram.)
