So much for solid wood cabinet doors. MDF on my 2023 Newmar New Aire cabinet doors.

Curious, what about the other doors in the coach? Did you pull any to double check if they are solid wood? Just wondering if they made that door MDF to deal with the "heat" in that cabinet

As in the OP all appear to be MDF. Here is another pic of even the tiniest of small doors above the theatre seats. You can see the mdf the holes for the hinges exposes.

Maybe the use of wood product would be less confusing. Cardboard (that's the word I use for it), is real wood product. It is worth defending because finish is applied and not a product of quality craftsmanship. And yes it cheapens any product made from it. I sometimes used it back in the day for router templates, never something I would sell.

But I am a lone wolf in this day of cheap products.

A few years ago we re-did the kitchen downstairs. I was amazed to find that high end cabinet suppliers use MDF cores or laminated Plywood and veneers. This approach does offer some finish options and i was educated as to how some of these done right are extremely durable. We ended up going with WEN. So far the stuff is durable, east to clean and we don't worry about it getting wet. In my motorhome finish damage from splash water in the kitchen and bath is evident. For my house down if Florida I became the king of Pergo for flooring and are even doing some walls in laminate. My motorhome is still carpet in the bedroom. The ugliest carpet you can imagine. Considering Pergo Premium with the foam cushion. As much as us older purists think only real wood will do there are some advantages to something else.
For my career I managed an automated warehouse. Every pallet was on a custom plywood carrier board. 46 X 54 X 1.25"thick. We had about 38,000 of these boards. My first intro to replacing them learn how specialized plywood products can be. Wat back then Rutland Plywood was suppler. They also made plywood for use as gun stocks.

MDF has its uses, but one of its major limitations is use in any application involving articulation, hinges of any kind and fasteners. That’s an IKEA recipe for failure.

For moving vehicles there is another downside! Weight!

There of course is quality differences in material and there are fastening methods, mostly inserts that can get past that. All in the engineering.
