This weekend I took my daughter for a walk in the RV park and left my wife at the camper to rest. While we were gone, my very absent minded wife decided she would fill the sink in our popup with water to soak some utensils to clean them. She turned on the faucet and quickly started doing something else and forgot about the faucet running. Water overflowed out of the sink and started flooding the camper. She realized her screw-up and turned off the water and started drying out the camper. But water from the sink spilled over the edge of the counter where the sink is mounted. There is plastic edging around the counter and the counter is Formica laminate on top of particle board. The particle board soaked up water and swelled up to twice it's normal thickness on the edges. So this fall I will have to build another counter top.
