Humorous after the fact

[GallenH]

We head out of Phoenix with a goal of camping in the White Mountains. At c.9000ft it’s much cooler than down in the Valley. After going through Payson we head on the 260 up the climb to the rim. About 2/3 up we experience a very loud bang from driver’s rear of RV. I think tire. But handling remains ok with no shimmy. About at the top of the climb, another bang. So I get off at the visitor center at the top of the rim. All tires ok. I check airbags. Still at the departure PSI. Engine compartment looks good. Nothing dripping under the RV. Engine temp good. So we continue. It’s about another 3 hours to destination and driving is smooth. No issues. But getting up into the White Mountains there’s another bang. Wife googling backfire now. Not much I can do about most the causes but I decide to check the air cleaner when we get to campground and engine cools. After setting up camp I decide it’s time for beer, chips and salsa. Discover that all 3 of our bags of chips have exploded. Five hour drive home uneventful.
