Cargo mat

Should I remove rubber mat from cargo area of Chevy Express before installing turckmount equipment ?

Yes. It usually has underlay that of it gets wet, it never dries out and causes rust. I like to have a Line-X or Rhino linings applied. Offers great protection

I wouldn't. The mat will probably trap water causing rust. Anywhere you drill holes should be cleaned and protected with some type of sealer or rino liner to prevent rust.
Just my opinion.
I don't have any mats in my cargo area.
