What about the head/toilet. Was thinking of the peat moss toilet. Natures ... something? Has the urine diverter, Does anyone have one? At $1k it's a pricey toilet, but I can see the versitility of one.
What hot water heater would you use and is a "standard sized" gas tank big enough? I know a lot of guys use smaller ones, just curious on these items.
What I like about the Nature's Head (
http://natureshead.net/) and AirHead (
http://airheadtoilet.com/) units--at least for what I have planned over the next several years--is the relative ease of installation. No water supply to run for aid in flushing, no black water tank to install or empty, lack of odor when compared to most all other toilet types, and that I will be able to easily remove the complete unit to use in a base camp or off-grid cabin instead of the van, then put it back in the van when I hit the road again.
I've read more than one review from people who don't do the full install with fan and vent and have no complaints even in small spaces. It's the separation of urine and solids that makes it smell so much
less and overall work so much better. Every time I flush a regular toilet now I am amazed at the huge amount of water wasted. As for fan/vent, I don't see that it would be difficult at all to have them in place in both van and cabin. This kind of multiple location usage makes sense to me and makes this type of commode a lot more appealing financially. I suspect it will outlast me, most likely. Additionally, other marine/RV toilet units have incinerators to burn waste, or moving parts that wrap and package waste, which to me just means more parts that could fail to work properly, break, or need replacing. Then you're potentially stuck with no ******tter for awhile.
As for water heater, I've been contemplating a propane-fueled on-demand unit like the Ecotemp (
https://www.eccotemp.com/portable/), that can provide for both shower and kitchen, again, in a more portable style for vehicle, base camp and cabin/off-grid home. Mounted on one my my rear or side van doors as its regular place, I'll be able to use it for a number of things, in or out of the van. Might even rig up a simple diverter so it normally feeds a line to the kitchen area, then can be easily switched to feed a shower hose.
Another water heater solution I've been pondering are units like Espar or Webasto that can provide both heat and hot water. Espar may not be making the combo units anymore, not sure, as the main Espar guy I know is Espar of Michigan (
http://www.esparofmichigan.com/products) and the only Hydronic units he has listed currently are for heating vehicle coolant. I know a slew of guys from my expediting days that run Espar air heaters that run off their diesel tanks and love them, though I don't personally know anyone who has a combo air/water heater. What I like about employing either an Espar or Webasto for heat and potentially hot water is that they draw directly from the diesel tank as I run a 6.6 diesel.
Here's a thread from a Sprinter forum a year and a half ago that talks about a few different hydronic air/water systems:

Efoy 210
Planning to order one next month for our Kimberley Kamper.
Here's an interesting article from Jan 2015 on hydrogen fuel cells, mentioning the Efoy 210 and the Dynad Hydrogen 150:
