I'm thinking about the opposite swap. As such I'd be interested in your take out, if you have no plans for it.
As far as the possibility of doing it, it shouldn't be hard. EVERYTHING in our coaches is built to print. Winnebago can tell you exactly what parts you'll need to make it look like it was never there.
(I should mention I have an Adventurer. I'd be putting it in under the fridge. My take out parts wouldn't help you, even if they did match, or I'd offer them right up.)
Gosh, just remembered there are two different types of dishwashers used in Vectras depending on the model. I'd need a drawer type one, the 18" wide full height one would never fit in mine.
