Thanks for the other suggestions on showers. I'm going to think about it.
$250 is allot for a shower BUT it will allow me to shower in "stealth mode".
I have been checked several times by rangers to see if I was collecting grey
water in the portable shower.  So now I have this big bulky shower and an
even bulkier shower grey water collector. Top that off with the Coleman Hot
Water on Demand and I've taken up half the storage in the van. This thing
that goes on the back looks like it's just another extension of the van and
will probably lead to less "inspections" by those in charge.

Yeah, I have a grey water collector at the bottom of my shower so you're now
standing in a puddle of water.  Of course I look carefully around and wing
the water into the woods when I'm done.  Yeah yeah, the soaps biodegradable.

Regular campground showers, now THAT's scary.
