Thanks for the first two suggestions. There is always a wealth of ideas and information from kayak fisherpeople here!
Is it better to mount the kayak right side up, or upside down? I have seen people do it both ways.
I'm thinking about aerodynamics and a secure mounting for freeway speeds.

I have enjoyed a small motorhome before, but I like the idea of a smaller and simpler camp van. The less encumbered I am, the happier I am to be an adventure traveler.
I have a small kitchen sink nozzle adapted to a pump sprayer for washing my kayak that doubles as a simple shower. If I need privacy for my "shower" I can sit in a big plastic storage box from Costco for $8.50 that doubles as a storage box ;-)
I bought a tri-fold 6" memory foam mattress that is outstanding for comfort and warmth, and it stows easily in a zipper bag for protection.
I have a small portable toilet that works perfectly. The bottom pops off like a suitcase and is discreet. It can easily be dumped at any service station or fast food restaurant along the way. MUCH easier than the way I used to dump my motorhome.

What more could a Caveman with a kayak wish for? (Maybe some kind of small portable flat panel TV for watching movies streamed from my ipad or iphone?)
