I am trying to get an idea of how much I should plan to spend for a conversion (ballpark figure). I plan to buy a used high top long bed empty cargo van. I have a place I can do the work and the tools (at a friends house). The estimate I am looking for is for parts only. I will likely hire my friend to work it and teach me as well. Here are the two builds I am looking at.

Build 1 (ideal): sleeps 1, internal shower + toilet, a/c + heat, microwave, stove, sink, lights, power receptacle, dry dockable with solar (7 days).

Build 2: sleeps 1, external shower and portable toilet , a/c +heat, microwave, sink, lights, power receptacle, dry dockable with solar (3 days).

estimates without the van cost. Storage is not important because I plan to pull and convert a small cargo trailer which is a different project

I'm a little surprised that someone has not suggested going to the Sportsmobile website. You have a choice on picking your brand of van and then picking your floorplan. They have some sample pricing here.. They do what you are asking about doing. The only difference would be what profit they are expecting - you would not have to spend that amount. And...you might buy a lesser expensive van than the one they order for you.
