Welcome to the CRVL Forum
Getting things down to the bare bones has to be the first step if you didn't buy a cargo/delivery type of Van that
is bare to start with from day one. But even then you usually have a bunch of clean up before you can start.
I'm sure you'll enjoy your project together and with the coming of the fall season the temps will be more agreeable
to build and later to travel in.
I have a couple of links below that may be of interest to you now. The first is for converting a Van, Trailer, or Car (or a extra high mileage "Bug Out Car" which is kind of a one person RV)
The second is for planning where you would go once on the road, useful places to know about while you are out there, weather & climate safety, and a links portal. It can be useful to plan while you ready your Rig and to use once you are out there on the road.
All the best with your build. :thumbsup:
