We’re looking to buy a used van conversion, but sooo many have synthetic grey carpet type stuff on the walls that I don’t really like* (see pic).

Ideally we’d like to put wooden cladding over it, but I’m wondering how practical this is in a van that is already fully kitted out?

Is it something that NEEDS to be done at the beginning or is retrofitting a feasible option for still getting a nice result?

(*No shade to anyone who has this - it’s just a bad association from childhood for me!)
