Bit of a propane noob here, figuring stuff out googling best I can, but the vendors' CS reps aren't forthcoming with answers to end-users with unusual use cases.
I will be having a certified propane dealer do all the fitting and installation, have them train us on the (yes I know critical) safety procedures etc, but I really want to know what I'm doing, have the list of fittings ready before I approach the certified techs, or they're likely to turn me down for liability red flags.

I want to purchase new lightweight portable DOT tanks that can work either horizontally or vertically, and will service vapor (cooker, fridge, space heat) as well as allowing liquid withdrawal as needed.
I've narrowed down to aluminum 43.5
A. forklift-style, adding a vapor service valve
but haven't located a vendor that will confirm the "optional plugged" 6th hole is actually available, port C in this diagram: http://www.cruisersforum.com/forums/attachment.php?attachmentid=48169&d=1350083660
Apparently Manchester's current models don't, so now I'm looking at Worthington. Or I swap out the center view guage for a vapor service valve, but making that work safely for horizontal vapor service may be a challenge.
or Plan B: same form factor, but vapor service cylinders designed for tractors/mowers, swapping out the stock (I assume one-way) fill valve for a fitting that will allow liquid withdrawal, most likely from horizontal-only, but I could live with that.
I'm hoping to find a member here that can directly give me detailed help with this project. Otherwise maybe someone can recommend a friendly vendor, or refer me to a certified tech in the biz willing to make some calls for me on a consulting basis?
And of course happy to entertain any and all suggestions and constructive discussion, but would prefer to avoid derails; e.g. I'm fully aware of the safety, legal and liability issues, thanks.
As a side note, anyone know how to get certified in this stuff - online, distance learning, or SHORT courses if onsite attendance required - without being currently employed in the industry?
