interrior paneling

[huron52]

Someone asked this question a while back. Then someone answered it with the link. Can't find it now.
I am going to open up the inside of my trailer and just in case I might damage a panel anyone have a link as to what it maybe called and where I can buy it? Also the tape like material that goes on the seams?

thank you

When I had to replace paneling in a 10 year old trailer, I found the closest dealer, and I was able to secure the matching paneling through them.
