I am using 5mm plywood which is thinner than 1/4″. This provides light weight and flexibility. Some of the panels need to flex to hug the walls closely. I am using riv-nuts to install the wall panels. I want to be able to easily remove the panels in the future. I hope I never need to remove the panels, but what that option.
You might wonder why would you want to remove the wall panels? I want to be able to inspect between the walls for mold and moisture. Also, I may have electrical wiring behind some of these panels. Having the panels easily removable make it easy to add or adjust wiring.
Finally, what if body work needs to be done on the van? I really don’t want to think about it much – but if there is and accident and work needs to be done on the van, I may need to remove wall panels and insulation. Hope for the best plan for the worst….

The Riv-nut tool is required when building a van. This tool makes it easy to make secure connections to the vans frame. I use this to secure the floor, wall panels, and the upper cabinets. I decided to use only three bolt sizes in the van build. 1/4″-20, 5/16-18, and M8.
