How many of us are there? Owners of Dodge based RV's?

Oh, I do know someone who does use his 'onboard' shower while camping in remote places. But, he re-plumbed his water system to draw water from nearby lakes and river in order to use his shower a lot. (Last I heard, he was thinking of going to a tankless water heater, in addition to the fresh water heater, for showering.

According to him, he'd need a trailer with a 250 to as much as 1,000 gallon tank to keep up with his showering for more than a day or, at most, two.
