RV Repair: Water Damaged Walls, crown staples, 3m products

Question
I am repairing a water damaged wall and would like to know where to purchase similar wall panels or please suggest another product that can be easily used and where to purchase. Is there a specific process that I should follow before I tear into this project?  There are definite "soft spots" and a musty odor in a closet.  Oh, the roof has already been repaired and everything else caulked.  Thank you, Les

Answer
For you wall you wont be able to match exact but sometimes you can get close. Try mac @ 1-800-234-2401 or call royal supply @1-800-777-7117. If you have to glue them use 3m 1357 if wood to wood if not then nt-30 both 3m products grainger can help if you can use small crown staples.
