It doesn't make any sense.
It's unlikely that both auto shutoff valves
would be stuck at the same time on 2 new lp tanks.
A stuck valve is usually the reason if you can't
fill the lp tank.
If you were able to put in 1/4 gallon,
then the auto shutoff valve is working ok,
and the tank was almost full.
We have 2 propane tanks on our westy, and
we keep one turned off, and only use one at a time
until it's totally empty.
Then we keep the empty one turned off, and use
the full one, and have the empty one refilled
when it's convenient.
Basically we use only one tank at a time to
keep track of usage.
You can use a magnetic sticker on the
left or right side of the dash as a reminder
which tank you're using.
If I were you, I wouldn't worry about it right now.
Just use only one propane tank until it's totally
empty, and see how long it goes.
It's also a good idea to run them totally empty
once in awhile to get the "gas odor additive"
out that collects in the bottom of the lp tank.

Kind of embarrassing ... but,
I'm suddenly having a problem getting my
propane tanks filled.
Tried 3 fill places today.
Background  ....... new stock tanks & regulators
installed 4 weeks ago.
Both been filled 3-4 times previously with no problem.
Now neither tank will take propane.
Actually they take maybe 1/4 of a gallon and that's
it.
Its been 2 weeks since the last fill and have been
running the fridge, furnace and cook stove constantly.
Is there something in the fill procedure I'm
forgetting?
On the Road,
