Were building our rig and want to use wall panels to speed up the process. Its not a skoolie per say and it has straight walls and a pitched but flat roof. No curves or rounded roof.
Home depot sells a 4'x8' white mdf "shiplap" wall panel
that looks pretty darn good in person. We could do the whole interior for ~$300 with this, vs 1200-1800 for real shiplap. I know real shiplap would look nicer, but this is version 1.0 of the build.
The interior walls are all sheet metal with poprivets. My plan is to poprivet some furring strips and to use construction adhesive + nails to attach the wall panels.
Anyone else done this? Any tips or issues you ran into?
