They are not designed to sit on either, unless in the "bed position", I would doubt they would honor a warranty claim since it's pretty clear this is abuse not normal use. That being said, in Fon du Luc I'm sure you can find a cabinet shot willing to make it for you, probably within a few miles of you. LOTS of shops in that area ! LOL and, you get to pick out your laminate color texture etc..
From what I have read ( do not have our rig yet) Jayco is using a thermofused melamine for counters not a high pressure laminate. HPL would be much more difficult to break, scratch etc... Good luck !
