anybody ever install wallpaper inside their RV?

I renovated the bathroom in our Class C back in 2016. I installed new wallpaper on a section of the (new) hardboard wall, behind the sink/vanity and toilet.

The wallpaper I selected was designed for bathrooms, moisture resistant and washable (available on-line from Lowes). Graham & Brown makes kitchen/bathroom wallpaper under the "Contour" brand.

I discovered after our first wallpaper hanging attempt, and subsequently talking to the wallpaper manufacturer, that I needed to prime the (new) wall surface first. This is so the wallpaper glue wouldn't be sucked into the new (hard)board. Our second wallpaper hanging was successful. Wallpaper has stayed in place for 4 years now.

I used prepasted, but purchased seperately the vinyl on vinyl paste which is usually used to put a border over vinyl wallpaper. It's been up at least 8 years, no loose edges.

I used pre pasted wallpaper from big box store and spent the next year repasting edges where they curled up!

DW has covered paneling several times. There is a base coat paint that you apply first, which gives the wallpaper better grip. On panels that had grooving, she used spackling to fill the grooves, than painted the base coat over that. When we moved several years later, it was still stuck well. She has also applied trim strips to some of the walls in the MH.

I have been busy doing the opposite, painting over my wallpaper. Time to get rid of the dusty rose and teal pattern. Maybe think about just painting it as well.

Should be easy to do.
