I'm looking for an easy way to refill, or at least partially refill, the
little 1lb propane bottles we use for our BBQ grill.

Has anyone added one of these to their Westy?

Seems to me, though, that it wants to be below the "waterline" of the
van's LPG tank in order to put much more than gas into the little
bottle. And it's not clear how a fellow would add this thing into the
existing main service valve > regulator setup.
