repair canvas window 2016 Palomino ss 1240

[Melvin Bell]

I am looking at a 2016 palomino ss 1240 popup truck camper. everything is good except the windows and screens on the side were scratched out and torn by owners dogs. How hard to fix. can new canvas be bought. can the canvas be removed and taken to a shop to be repaired. Any advise appreciated.
