Oh, I was hoping nobody would ask...it's kind of embarrassing. But I ilke a good project.
Let's see, I probably have 2 hours in cutting styrofoam and hot gluing it together to get the basic shape, then an hour or so carving it (so that it has a low spot for the drain, an indentation for the rear leaf spring support, and another indentation for a floor bolt), 8 hours in epoxyglass layup....another couple hours in dissolving the styrofoam inside the tank. 1 hour putting in a pvc drain pipe (3/4 inch for a fast drain). I have started the job of putting plumbers tape (with chafing material) under the van to support the tank and I have probably another 2 hours before I get it in.
So that's about 17 hours so far. There is also a few hours in shopping for parts.
Patience is probably a prerequisite for something like this.
I found out during a leak test today that it will hold 5 gallons instead of the 3.75 that I incorrectly calculated.
oh, and I also wired in a water detector at 3/4 of the way up so I will know when it's almost full.
