My hardest job is to become a minimalist by thinking about the least amount of things to bring at the smallest form factor possible. Even with the rear seats removed space will be a premium.
Utilization of space available is the game plan. Finding square items that use less space has been interesting, but accomplished.
I look forward to showing everyone the conversion with no holes being drilled in the Prius, that was also a goal. I did not want to change the Prius in any way that would be permanate, unless I really had to. So far so good.
How to have privacy in the rear was another chalange that I only solved this past weekend with some clips I made for the curtains.
I needed to buy some cooking things to save space. This saved a lot as another goal is to keep from moving things from my sleeping area to my sitting area each time I move. This is not what I wanted to do for 3 months. I think I have a good handle on this although not totally resolved yet.
I was asked about a trailer hitch carrier or roof carrier and yes these would be possible, I didn't want to do it as a crutch to carry stuff I use once or twice, or like last year when I shipped things home to make space in the campervan. My Priusvan will be much leaner but in se ways better. As a woman who has been using her Prius to do this for years, if a backpacker can carry what they need we in a Prius should be able to figure it out.
Now to packing everything and see what doesn't fit and then the decision on what goes and what stays.
There will be some pictures soon with my solutions.
