Today the black and grey water system design was finalized. With a model in place for each of the tanks, I was able to plan out how the tanks would drain while making sure there was still enough room for ground clearance. As it turns out here are the final specifications:
-Black tank: driver's side, 29 gallons, 9" ground clearance, 3" exit from rear to drain system
-Grey tank: passenger side. 25 gallons, 9.5" ground clearance, 1.5" exit to drain system
-There is a 1/2" drop from the grey to the black tank to allow for gravity flow. Both tanks will join into a Valterra T80 double valve with pull valves facing straight out the driver side for easy access.
I also got the vent tube cut and checked its placement relative to the roof vent; all should work.
Tomorrow I'll take the models out to Abbotsford to get a price estimate on making the actual tanks. I'll also start prepping the inside of Redford for the 3 windows being installed.
Calvin here - after spending almost 33 years in education as a high school teacher, elementary teacher, and elementary administrator, it was time to retire! I did so happily and with no regrets; it was a terrific and fulfilling career. I do enjoy building projects as the design and building process is very therapeutic and you see a completed functional product in the end. Now to combine the build with another of Angela's and my passions - travel - is something we're really looking forward to.
