I assume you want to feed your existing system without modifications so I would recommend you get a 60 or 100# cylinder from rural king/tractor supply/menards (they all sell them) then go to your local LP gas dealer (not a reseller) and purchase a 1/4" hi pressure adjustable regulator and full flow pol fitting(rego 597FA or fisher 67 series) with the adj range of 3-15 psi, you do not want to exceed 20-30psi in your hi pressure line do to the possibility of re-liquidification, Buy the hose lenght you want, I recommend hose with 3/8" female flare ends as you can always adapt back to pipe. Then you will need a marshall excellisor ME393 which is 1 5/16" male acme (QCC connection) to 1/4" female pipe that will allow you to connect to your existing pigtail and use your "hose" regulator with out mods.
Hope this helps
PS most plumbers dont have a clue on this as they work with the low pressure side(after the "house" regulator)
WOW! Helps... Heck yeah! Thanks for all the assistance. I'm glad I posted here. I was originally going to buy a full flow POL fitting, a 5' 1/4" hose from Mr. Heater and a 1/4" QCC1 fitting (again from Mr. Heater) which is very similar to the ME393 with the exception that it features a male NPT fitting as opposed to a female.

So using a regulator upstream of my campers onboard regulator isn't going to hurt anything? I was always under the impression that the low pressure side of the system operated on something like 1 PSI so this would still be higher but I was still leery of the idea. I looked at the models you listed. I assume there's a quality reason these are more expensive than their competition. The price is fine with me (can't spend too much for safety.) But the size is a little bulky. Is the model I'm linking below worth consideration at all?

I also found this regulator and hose combo

Also 1/4" hose will flow the volume at the higher pressure. But you still recommend 3/8? I've found a couple of hose options but the one I had planned to use was this.

At the risk of getting a lecture about internet advice from others. I'm going to say, you sound the most knowledgeable of anyone I've talked to. As you say, plumbers have no clue about these questions. The smarter ones admit they don't know. The rest have just tried to BS me.
I will also say please point out the flaws in my components and plan. I don't want to run out of LP. But I REALLY don't want blow myself up or damage a propane component by feeding it with liquid and not gas.
