At this point the next few videos all come into play with one another. The structure, insulation and layout with the kitchen cabinets. I wanted to separate them so you didn't have a 20 hour video to go through it all. Structuring everything was by far one of the trickiest bits. The video will be a good tool for this section.
One of the very first things that had to be tackled was having something in the ceiling that I could bolt things into. When you look at your ceiling you'll see support beams running across and if you are lucky like I am they will have little holes you can feed bolts down through.
*** The only thing to watch for when tightening the bolts is that you don't tighten them too much. You want it so it won't wiggle, but if you watch as you are tightening you are actually pulling the van roof down too, which isn't good. ***
Once these beams were in place I now had somewhere to screw a base layer of wood across the ceiling to attach my pine boards to (you can see it in the last photo on this post) and it also more importantly gave me a place to run the beams that go around the doors and the whole length of the vehicle. I apologize in the video calling them 45 degree angles, they are all 90 degree brackets. Do watch the video here so you can see the gap you need to create for the door to still shut. These photos don't show it well.
After the beams running down the length of the van and around the doors I put in the wall between the front on the back. Many people will close this off entirely and work with a slightly different layout inside. With Baron traveling with me I wanted him to have freedom to walk between the front and back, and to cut down on blind spots driving so I could see out my passenger rear window. You will see these walls have many functions in my setup.
*** Make sure when adding this wall in that you leave enough room behind your seats for them to move forward and backwards for taller people who might need to fit. ***
The only other bit of structure was having a place to attach my pine walls to the sides. For this once I had my counter top in place and my seating area in, I ran a few pieces of wood vertical so I had places to nail that wood into. You can see them on both sides of this picture. This was the only way I figured out how to have a flat area as well with so many curves on the inside walls of the van.
Also to note ... the pine planks I used is very light weight. If it were any heavier I don't think it would have worked and would have potentially just fallen off with the weight and movement of the van.
Good luck with this bit. It is by far the most custom and most important piece for my van build.
