Hi ! Welcome to IRV2! We're sure glad you joined the gang!
I've never done that but I don't think it would be a huge job if you're a pretty good handyman. You would need to find a good cabinet shop to work with you on the project. The first problem would be finding an RV oven to fit the space, possibly from one of the RV salvage yards.
Good luck, happy trails, and God bless!
