INCREASING lpg capacity ?

Are older tanks worth the effort or the expense? Does anyone actually check dates of manufacture ? Best to just buy new ? Best deals ?

Two answers:
For "luggable" tanks. Yes they do check the dates. however many places can re-certify and you are good for another x years (10 I think but don't quote me)

On "Fixed" tanks (IE: class A) some will and yammer "out of date" but they are not supposed to do that..

Increasing capacity.
Luggable tanks easiest is to get a 3rd tank. or even easier. With a two tank system you have an auto-change over regulator.. The arrow on the manual valve points to the "in use" tank. and the indicator shows Red or Green. When it goes to RED flip the valve .then close the tank valve on the now empty tank and get it refilled.. when the other tank shows red. Flip back and .. .this goes on and on and on.

I had a single tank luggable trailer and a spare tank. Same process only when it went RED I changed tanks..

NOTE method 1 is how we did it at my parent's house for a lot of years with 100 pound luggables.

On a Class A. if you need to extend your stay.. Well Extend-a-Stay used to be made by marshall Brass (I think they discontinued but do not know if they brought it back) Stay-a-while, is a competing (identical near as I can tell but.. not all that "near") device.

It goes between the Valve on the tank and the regulator.
It has
One POL male fitting
One POL female (These are still used on Fixed tanks)
One "Quick Disconnect" fitting capped This is like a throw-a-way Propane bottle (the 1 pounders or there abouts)
And an "inlet" (This is a smaller plugged fitting)

Comes with a 5' "inlet" hose (Well some of 'em do) and optionally a 10' Quick Disconnect Extension hose.

Hook your Gas Grill to the RV's tank
Hook your luggable grill tank to the RV
Works both ways.
