Camper interior wall covering

I'm currently exploring different options on interior wall covering for my OVRLND camper.
...What are folks using in their campers?
I'm open to all suggestions, but hoping to keep it light, easy to keep clean, and durable.

Looked at Coroplast. It's light and easy to keep clean, but appears as though it might not hold up well over time.
Thought about "door skin", (thin ply wood). It looks great, holds up over time, but not very light.
Carpet Squares... They look good, hold up over time, not that light, and hard to keep clean.

If anyone is using Coroplast, please let me know how it's holding up.
This is by far the most inexpensive of the categories above.

Cheers

 

The coroplast/sign material is a great option I think. It's really lightweight/thin/you can splice it to make clean bends around curvature. Use a quality spray adhesive and pick a nice marine grade fabric to line it with.

I've used this material to do exactly this on the walls/ceiling in a van build. It's thin/lightweight, and is very inexpensive, so if you fuck up it's not the end of the world haha. Wrap it in a good fabric, use a good adhesive.

You could even make a custom laminate. Glue foam insulation board to cloroplast sign material with fabric wrapped over it and you have nice insulated wall panels with a nice fabric cover.

 

Insulation would be my primary objective.

 

No affiliation. But this guy talks about different options.

 

Thanks for the replies.
The insulation is complete.
In the end, I settled on Coroplast for the covering. It's not completed yet, because I'm just picking away at the project between chores. The ceiling and some of the walls will get marine carpet. I'm using 3M spray adhesive to keep it in place.

Cheers
