Fellow RVers,

I tow a 5er with a Dodge V10 dully. I have been looking for an auxiliary gas tank to put in the bed of the truck that will set level with the sides of the bed. Almost all the tanks I see are diesel or cost in excess of 1000 dollars. Does anyone have any suggestions on where to get a gas aux tank a little cheaper?

Thanks,


Mike

Have you considered a set of "Jeep" cans. If you carry 10, you will have 50 extra gallons. The will fit below the truck bed as well.

Good luck.

I think I remember seeing rather small transport tanks in Northern Tool catalog.
Transferflow sells aftermarket poly tanks that fit under your bed, kinda pricy for the size in my opinion though.

I may be wrong, and if so, some will correct me, but I think that in-bed GASOLINE tanks are illegal, that's why you only see them for diesel. The under bed tank is what you will probably have to get.

I think Stan may be right - permanently installed gas tanks must pass federal crash-worthiness specs and I think that in essence means they must be mounted between the frame rails and well forward of the bumper.

When I inquired at Transfer Flow several years ago about a tank for my vehicle, they explained about all the specs they must meet to certify a tank for a vehicle. They had a tank that would probably fit but would not sell it to me without certs and they did not know when or if they would certify a tank for my vehicle.

There's another consideration that no one seems to ever think about: weight.

Once you add an after-market fuel tank and fill it up with fuel, are you going to have enough towing capacity and payload capacity left over to pull anything larger than a popup?
