I found some tanks at Tractor supply today that ranged from 30# to 100# tanks and it said they are DOT approved but there is only one valve on top like the BBQ grille tanks. can these tanks be mounted sideways? do I need a tank that has both valves?

thanks!

 

I think ya can, couple problems i see are at from full to 1/2 you'll get liquid, after that vapor.
Only one valve could be a problem, if you want only vapor out of it or liquid only. Not sure on the wall thickness, but i bet they are not as thick as one built for truck use. 60 gallon saddle tank i have is pretty heavy.

 

I think you will find that the DOT aproved stamp is for transport use only.

 

What you need is a propane tank like is mounted under the floor of an RV. Try an RV dealership, just don't tell 'em what it's for. :-X

 

You can also find used tanks at salvage yards & propane suppliers.

Good luck.

 

go to your local propane distributer and get a propane tank for a forklift those work on their side
