Alan, Thanks for the reply. I took a look at your pictures and like your tank and filler set up. I have seen some of the tanks mounted like this and fill through the bed. Anyone have this set up and does it work ok for you? Alan I see you play guitar. I have built a few and my son plays them. This winter I built two hard guitarcases for him and coated them with the dupli/color roll on bed liner and it made a nice finish on them. Got the idea from local Amish buggy shop. Well sorry I got off topic I did not check on the salvage tanks to see if they poke them or not yet but hope to soon.
