Exterior panel replacement.

[Bradbo]

I have a 1992 Jayco 1206. I want to repair the front lower panel that’s dented and allowing road dirt to enter into the section where the pop up cables are. Can someone buy exact replacement aluminum panels or is there a place someone can buy a replacement panel made from aluminum diamond plate?
I also have multiple holes on the kitchen sink side where I tore out all the gas appliances and replaced them with electric appliances.
