Winnebago breakdown - #1

Driving along happily screaming to eachother (Winnebago super loud), Pola and I overhear a very loud pop and fizzy sound. We pull over to the side of the highway in Missouri, and take a look around. Wheels intact. We pull up the hood, pretend we know what we're looking at, close it, and then continue on our way. When we continue to drive, we notice that the heat gauge is all of a sudden increasing more than before and the A/C is no longer working. We drive for a few hours, and then decide to call Pola's dad, who tells us to find a mechanic immediately. Oops. We pull over the the walmart.....get some parts, lots of coolant and oil, some food, toilet sanitizer, and leave after a few hours. Had a wonderful employee at Walmart stay after hours on labor day weekend to help us out and get us back on the road.
