Tiny House Truck Build

I was asked to update my Tiny House Truck post to include the build because I had to design things from scratch like my Evaporative Aircon, Electric stairs and Skylight, hopefully it helps someone.

That is a great effort.
You said

either be enslaved by debt/rent and therefore servitude for the rest of my life or build the truck and do as I please.

I do not agree with this statement, there is no enslavement nor servitude involved in having a home to suit your needs, not you wants.
Many people have chosen a path of mortgage and feel happy about it when its less than rent.
Even in your case, the Tiny Home on Wheels would not have been created without assets and you have mentioned a few downsides already.

I think each persons choice is ok and neither needs to be maligned. My 1 cents worth.
