Im looking for any ideas for places to put air tanks under my truck. Its going to be used for train horns(bad drivers) and air lift bags for towing. I am looking for a size and place to put it. I have an 07 dodge ram 2500 quad cab short bed.

 

you could kill the spare off. It all depends on how big the tanks are. You might figure out a way on how to mount them under the bed. Or maybe just get a toolbox and put one in there.

 

check out where all the companies are putting the propane tanks and put the air tank there....

 

Most guys I have seen either hide them in a toolbox or mount them along the frame rails wherever they have room

 

For starters, I have a PacBrake, I mounted their 1/2 gal tank on the framerail under the drivers side front seat. When I installed that tank I added a 'T' for a secondary tank. From the 1/2 gal tank I put a check valve in-line to the secondary tank which is mounted next to the first tank on the frame rail. I use the secondary tank for accessories - dual in-cab air bag control, air horn, rear aux air supply connection.

You can purchase air tanks in all kinds of sizes, with an on-board air compressor you really do not need an enormous tank to have good usable air storage. If you check out some of the semi-truck junk yards you can get a good deal on a larger tank, but locating it under the truck is a whole other ball game.

Mine is under the hood where my 2nd battery used to be and my compressor is right next to it.
