I think it was around 30 hours. But the time was oddly distributed it, things I thought would be easy, like taking the cabinets out, turned into 4-6 tasks to figure it out and avoid damaging anything.
My big lesson learned was RVs are build as fast as possible, using a rough carpentry like style, I tried to approach it like a cabinet maker or machinist. I expected thing to be square, strait and even. In truth even the aluminum frame of the rig was not square. And I don't think they own a drill, everything is shot together with self tapping screws, so the holes can be almost anywhere in the frame or miss it altogether.
I had also never used epoxy to this extent(encapsulation etc). So it took me a while to get the hang of. The big lesson here for me was that 15 minutes is fevar ! you have time and don't need to rush even when working on the whole sleeper board. I rushed too much early on and put too much material. I set a timer and after I had the board covered in one coat I was certain it would have been 14+ minutes, it was 7. Also when using it on vertical surfaces use more thickener than you think you need, it thins a little as it starts to cure.
I took a lot of pictures but assumed I would have the project done in weeks, not months so videos would have been better. The little side cabinets are like a chinese puzzle.
Let me know if you have questions
