Cut a hole in the side of my vehicle.
I'm insulating with Thinsulate, and will have a 125v inlet installed in the side of my van this weekend, and a 14" square hole in the roof for a fan is in my future plans... the fan is sitting in my cargo trailer. Why stop now? #vanlife is upon me.

My intention was not to stop you, It might help someone starting a van build, in doing it correctly.
This guy actually brings the Tech and does not parrot anyone.

Electricity and ventilation, two musts. Properly sealed openings are not a problem.

I,'ve installed roof vents in all my RVs as well as solar and related wiring and never had a leak.

You are correct that if properly installed they are not a problem.
ET...…….I don't understand YOUR just posting links without SOME discussion...……BEST ?

All of these insulation techniques are different.....WHATS YOUR POINT ?

The last unidentified youtuber link decided on a rigid foam (celotex) for the van floors walls and ceiling ……….and mineral wool for cavities

^^^^sounds pretty familiar to the advice found on this site...….

THINSULATE is another excellent material...…..

"In doing it correctly " ?????????
in cold climates, the only option is a closed cell spray foam in my opinion if you have the money, the walls and ceiling will sweat and its not because the wave 3 puts out moisture, i insulated my van with polyiso then completely sealed everything with reflectix more as a vapor barrier, well it didn’t work and i literally had puddles of water in the ceiling, i had to rip it all out a couple weeks ago and lost a few hundred dollars in material, i just bought 4 armaflex closed cell sheets ( 3x4 ) to do my roof to see how it goes, i'll let you know how it goes
Since 2014, that I know of when I started reading CRVL blogs, Bob Wells has been telling people that Reflectix needs an air gap to be effective.
Not news.

You are funny. There are already lots of really big holes in the sides of your vehicle.  They all need gasketing to keep out water. Just cut a hole and do the gasketing job correctly and don't cut into the support structure that was formed into various shapes for load bearing. No need to avoid putting in a window if you need one or a hole for a water line or electrical connection, just choose the right spot and put in good gasket material to keep out the water. Oh and don't put air intakes into the vehicle next to the exhaust outlet or put stuff too close to a hot surface such as a muffler. Think it through before you do it.
