Transitpete,
I've taken a bit of time to think through the plans and spend i see when i list everything out, and reality (i.e. the wife) is kicking in a bit.
I'm going to stop trying too hard to fit everything in this space, it's just limited and i need to focus on making it work with reasonable spend.
So I've now got my twin seats back in second row, and i am going to put a cubicle in front of them with a thetford 565e toilet. The cassette style are easy more money and location is bad with the van side panel uprights to fit. I'm also going to put headliner back as you are.
I'm into insulation just now. What are you using again on the side walls?
I'm going to just use a small water tank for now under a sofa seat etc, just so it works enough to see how we use it.
I will be going back to the original idea of kids beds somehow across the van.
My next purchase though is the electrics. I still want a solar kit and hook up, but also split relay off the main two batteries. Just need to Google on how to connect to main batteries.
