Just looking at the construction of the cabinets in my camper, which is 18 years older, the joints of the structural pieces are all stapled or pocket screwed, and glued. Then there’s a thin plywood skin over that. It would be difficult to get any of it apart without cutting the joints.
Getting the counter top off would be do-able, but I’d have to pull the water heater and the stove out to get to all the screws.
Is there any possibility that new wires could be pulled through that area?
I wish I could help you more than that, but it’s probably going to be a tough fix regardless of who does it. And, part of the fix is going to have to prevent future damage.
