Removing it probably not a problem. Hanging "heavy stuff" on the foam core walls will be a challenge. Lots of foam. Spindly interior supports. Hidden electrical wires, coax & audio cables. In the RV industry there is the "plan" and the reality of "as built". Meaning stuff may be somewhere near where it is supposed to be...or not.
Pull out a couple drawers. Get a bright flashlight and take a good look at how that under cabinet area is constructed. Staple and sticks...industry standard.
We have a 14 View Profile. It also has a TV there beside the sink & under cabinet...bigger than yours. Doesn't take up usable space. Handy for catching AM news & weather. Or, nice entertainment when it is pouring rain for two days.....
