Please, please, please can I have more details and photos

I'm planning on making a similar sized micro caravan.
I used to have a Romahome camper based on the little Honda Acty pick-up so have seen what can be achieved with a small area.
My idea is to use a pick-up Truckman type top as the upper section.
Before I had the Romahome I bought two such tops and intended joining them together - with lower upside down. In fact I've still got the new double glazed windows somewhere.
This time I'm going to use just one top with a simple flat fibreglass sheet base.
I haven't thought out the full plan yet but I want it low so maybe a small "pop up" roof section to allow standing room or even have the whole Truckman top rise.
One thing is certain - it'll be detachable so it'll fit on my flat bed trailer.
