So I picked up a 70 gallon Freightliner tank for good deal, to use as an aux tank in the truck.  I'm now looking into the mounting of said tank.   I got the truck's tank straps and mounts, but I don't see a viable option to use these just yet, as far as mounting goes..  The tank is 23D x 41L.
Anyone here done this before with a similar tank?   If so, pics?

 

Thank ya,

Looks great. Do you have mounts figured out?

I'm going to use the OEM J-hangers from the freightliner, but I have to make new saddle supports.   I guess I'll invert them, and where the brackets would normally be vertical on the FL, I'll make that the bottom, against the bed-floor.
