Nice candidate project trailer, keep up the momentum folks, you're doing great!!
I used MDO back in 2011 and wrote about it here
Got to note the small lumberyard that supplied mine had MDO & HDO in thicknesses up to two inches - for not much money.... Our freshwater tank basement floor panels would be good candidates for the 1-inch, etc.
Just to note, the HDO (high density overlay) is essentially formica-clad without the finished color & designs, would ace interior cabinets and countertops where veneer or laminates would be the finish layers.
