I agree that professionally applied veneers are superior, however, most people don't have access to that type of high-end equipment Joshua, nor can they afford to have custom interiors built professionally.
For the DIY vintage A/S restorer, self-applied veneers can provide options &/or variety with different woods and improve the interior substanially. I fabricated the panels used on our new dinette (see photos), matching the original oak cabinets that are intact and of course, they are not high-end "furniture quality" finishes... the vintage cabinets never that level of finish, but they certainally blend in well enough with our interior.
Toaster, I would encourage you to consider reveneering your original cabinets as a viable option. Mock-up some test panels, finish them as you would in the trailer and see what you think...
BTW Joshua, I like your new bench...I'm sure it will be beautiful when it's done.
