I have one of those Extend-A-Stay tee fittings on my MH. This allows me to bring just the tanks for refill while set up for the winter. I'll fill the built in tank in the fall & both 30lb tanks. I'll run off the 2 smaller tanks switching them as needed. The main tank only gets used when lazyness kicks in & the 2 smaller tanks don't get filled right away.
The extend-A-Stay tee also allows me to hook up a grill to the main tank while out ASing.
