When the Zombies strike, I want to have at least as many resources as I can haul... Ha, ha... Sure, I let a tank run down until it auto switches, then I switch the lever to the full one and get the empty one filled up. Then put it back in and wait for the other to empty.
I carry full load of fresh water every trip too..
I carry way too much stuff that I never use, but just feel better having it none the less...
I used to carry my Honda 3000 generator, even going to full hookup sites, just in case the 'power went out' on us... Well, I got over that need pretty early on and have never thought about that since..
Anyway, weight is always a concern of course.. Just depends on what you feel you need to do for your setup.
Good luck! Mitch
