Quick progress report - got the water system and heating system in, and a quick 2-night camp trip to test it all out.
Main features of system:
- ability to fill 30 gallon freshwater tank from clean pressurized source (aka my garden hose)
- ability to use my water pump to ALSO fill the freshwater tank from a non-pressurized source (flip 3 ball-valves horizontal, and the system can now pull water from a bucket on the ground, or a stream, through my filter setup, and into my freshwater tank)
- when 3 ball valves are in normal vertical position, the system is in "normal" mode, with pump pulling water from the freshwater tank, through the triple filter, and out to the sink/exterior shower
- Rixen heating system, provides instant hot water to sink/shower, as well as heat to the camper (vent on floor, under dinette, and in cabover)
- Rixen can heat from both the gas furnace (mounted under flatbed, behind rear storage box, pulling directly from truck's fuel tank) or via 110v AC power - with the Goal Zero Yeti Pro providing plenty of power. Probably will only use this option when I've got excess battery reserves/lots of sun for solar recharging. But 8kWh of battery and 900+200w solar means this is a legit option, if I don't want to burn gasoline.
- Graywater is a 5 gallon jug, with a valve on top that allows me to choose whether the sink drains into the jug, or down under the truck. Also includes an overflow, so that you can't overfill the jug, and it simply drains under the truck. Quick disconnects so that you can easily remove and dump the jug.
- LED backlight for the jug, and for the main freshwater, with a momentary switch inside the camper, allows you to quickly glance and see your fresh/gray water levels.
above: furnace is mounted behind the flatbed's rear storage box (which I removed for the install). I've never washed this section, and in a year of hitting dirt roads, this area still seems clean, so don't think I'll have issues with it getting covered in mud... but I'll keep an eye on it, and install a shield if necessary (it's all weatherproof of course)
