All he had was a vice grips, nail from a tent, and a hammer that the park ranger was nice enough to lend us. Some other park workers said we couldn't use their angle grinder or any power tools because it would be a liability. Weiners. After several hours and lots of swearing Alex was able to peel the fitting off the old muffler like a can of sardines.
He finished up right before we had to check out, only to find out that the muffler he bought the day before wouldn't fit. So then we drove to Sandusky without a muffler to their Autozone and got another one that didn't fit, but the clerk at the store was awesome and let us borrow a pipe expander and combination wrench to try to make it fit. That was hilarious because you really need a vice and a big extender bar to use that tool. Alex improvised by wedging it under the camper tire and holding it there with his feet while I stood on top of the wrench, then we'd rotate it and repeat. A hundred times. In the Autozone parking lot. But it finally worked! Then we were off to Cleveland.
