At this time I’m more inclined to a 5th wheel. There is a RV show in about two weeks in SFO bay area. I will stop by to get more info.
To clarify a bit further, regarding the water supply, I was referring to “boondock”. I just need to get real world numbers. For example, two people boondocking for the weekend at Mojave, CA. Assume no dishes to wash even if so, a very little.
