Do any of these converted van mods consider weight or crash testing? There's a bunch of tile (maybe they're fake?) above the sink. That seems like a nice touch aesthetically but probably unnecessary weight. Also, pieces of wood or other facades on the wall could become projectiles in a crash. Perhaps nobody should be sitting anywhere besides the front two seats while the van is moving, but that means the van can only carry 2 people safely.
- It's all enclosed spaces,no communication to the driving cabin, so no "flying objects" should reach there.
- No certification necessary. That means it's considered "load" strapped to the chassis, and then, nobody can be sitting in the back while moving. Passengers can only seat in the cabin.
Edit: Also, it's a product for L2H2 size and bigger vans. I think some of them, specially if the cabin and the load space are separated by a wall, have three seats in the front.
The major companies who make RV have a standards body that they in theory build to their standards.
Additionally the van maker publishes an “upfitters guide” which explains what you can do and how to do it safely.
The more professional custom van builders will take their complete rig to a truck weighing scale before using / selling.
In general the camper vans are a lot safer than the big busses (class A) or regular RV (class c). The shell of the van and the front seats have to pass some safety ratings.
With the class C being made mostly of plywood, they usually just blow up when they are rolled over.
I did a lot of research on this before purchasing a Winnebago van. They seem to take safety a bit more seriously (ie the back seats are tied into the chassis and are from a known bus seat manufacturer).
That is in line with most campers. The market is dominated by rich retiree couples as young families usually cannot afford a camper van. As a result, most models are designed for exactly 2 inhabitants.
It looks like the wall with the shower creates a barrier between the cabin and camper portion. So stuff flying around the camper wouldn't be able to get to the cabin.
