I would leave the 6 Gallon hot water tank and use electricity & Propane at the same time to heat the water between showers to shorten the heating time.
x2. I have a 10-gallon tank and when I'm running electric and propane at the same time, I have an unlimited hot water supply -- or so it seems. I live with DW and 9 and 11-year old girls -- all with long hair. On our last trip, each of us took a shower -- me last (and they say chivalry is dead!). I'd say the shower was in use for the better part of 90-100 minutes and we never ran out of hot water. Of note, my shower was about 6-7 mins! :)
