..Thanks for the suggestions, and please keep them coming.
I will look into the 'extend a stay'. Have heard of those, but haven't checked into such yet.
More I'm thinking about it, I think a 12' hose should be enough. Will be nice if all I have to do is get an appropriate connector to mount onto the LP gas tank, and a 12' hose. Would MUCH rather carry a 12' hose with us, instead of an entire separate gas bottle.
I may also look into purchasing a smaller, portable gas bottle to use just for this. If I can find one a bit smaller than a 20 lb bottle, that is safe(r) to carry in a storage bin, that might not be a bad idea, either.
