Build, In What Order?

I’m having a tough time figuring out the order of operations to do a van build. About everyone I’ve seen does floors, walls, ceilings, and insulation first. What I don’t see them doing is roughing in the electrical.
Am I right in this perception?
Is there a reason for this?
Where do they run their wires if not behind the wall/ceiling panels?
Assuming you would do the wiring before the wall panels, would you do that before or after the insulation?

Just trying to get a grip on the big picture here.

All input appreciated.

Hi,

I did the insulation first, then floor, then wiring that runs from electronics area to other parts of van, then windows, then some of the bed/cabinets, including where the battery and electrical stuff was going, then installed batteries, inverter etc., then wall and ceiling paneling. Seemed to work pretty well.

When I did the insulation, I did not insulate the area where I planned to add wires.

Thanks Gary,
I learned a great deal looking at your build page.

I did the insulation after wiring and at the same time as installing cabinets.

First the windows and roof vent then I did the insulation then roughed in the wiring, ceiling, lower cabinet work, upper cabinets. I had the factory wall panels so they just got installed as needed.

I've saved the ceiling for last. I figure it will leave plenty of space for wires, insulation, MaxxAir fan, disco ball, funky LED lights,etc up there!

I am not done yet, but so far:
Note- ordering stuff has been going on before I did anything physical, and so I have stockpiled things I will need down the road. I plan, research and order what I will need in the evening. When I ordered the windows, I was committed. Big $ there.
1) floor, including insulation
2) insulate walls, ceiling (except for panels with windows
3) run wires over the insulation
4) cut and install lower rear walls
5) box in the wheel wells, battery and electric compartment
6) build the beds
7) hook up the charger and 12v system
8) anticipating installation of Maxxair fan, if the part replacement comes in tomorrow

Go on a trip, learn by using

Windows First?

Seems to me that the first thing to get done would be any window, ventilation or other "hull" penetrations.

Does that make sense?

We hacked the van sides first - - i.e. the windows.

Concerning wiring . . . much of our wiring has been 'fed' through the interior of structural support members allowing us to add/make changes to the wiring virtually at the last minute (we haven't insulated these members). HOWEVER, we prewired the floor for water (we have a city water connection on the driver's side that supplies water to the galley and fresh water tank on the passenger side) and several runs of 120VAC. There is, incidentally, a narrow, about 1", transverse (left/right) 'break' in the floor ribbing (halfway between the B pillars and the wheel wells that makes for a good spot to run transverse hose/wiring. Our floor is comprised of 1/2" polyiso under 1/2" plywood. We had to notch the polyiso above this transverse 'path' in order to fit the water supply hose (1/2" PEX A - - probably wouldn't use PEX A, now, but we didn't know better).

I strongly suggest making penetrations first. Cutting the metal leaves nasty debris that needs to be carefully contained. Much easier with an empty van.

We did major electrical runs before insulation and now consider that a mistake. I wish we had done insulation next. Also, I would have no overhead electrical runs if I could do it over. It would have been so easy to run it under the floor.
