Our experiences are similar to other inputs here. What I do to keep the cost down is not run the hot water tank full time and use gas when I do. I find the gas is cheaper. When we are in a park with good facilities we try and use the park showers.
One other thing is I have a couple Goal Zero solar generators I keep charged with solar panels on the roof. I use these for our lap tops, charging phones and tv watching in the evening. Every little bit helps.
Some of the friends we meet along the way have full time solar set ups, but that's just too complicated and up front expensive for a simple person like myself.
