When I was a teenager, my folks had a MinnieWinnie motorhome but never really went anywhere in it. The summer I was 14, my aunt and uncle used it to go to the mountains and took pity on poor Mikey and dragged him along with their kids. Woo hoo, our first trip to the mountains!
Getting there was uneventful, but when we arrived we learned that nobody had any idea how to make the refrigerator work with LP. Ended up having to get some people from another campsite to come show us how to light it and all. Had similar "fun learning opportunities" with the black water system etc.
We were staying at a campground near Eagle Nest lake, and my cousin and I were desperately wanting to catch some of those rainbow trout we had heard so much about and seen in "Field and Stream" since we were boys. We raced over to the little tackleshop, bought salmon eggs and such, and out we went to fish. We fished up the lake, and down the lake. Nothing. Went to the little river that flowed through the campground, and fished and fished and fished. Nothing. Went back to the tackleshop the next day, bought different bait - and repeated the sequence. Still nothing. Third day, we went back and tried lures. Still nothing. We were so desperate to catch a trout we were ready to dive in and grapple for 'em. Not even a dadgum nibble, although other people with exactly the same bait and such were pulling them out like cokes out of a vending machine. On the 4th day, we went back to the tackleshop ready to try anything and the lady working there looked at our sunburned, crestfallen faces and said, "Hold on boys... " and went back in the back. She came back and tossed me a white paper-wrapped package and said, "Now you can tell everybody you caught some rainbow trout... "
Inside the paper were about a dozen cleaned frozen trout!

Boy the family gave us fits about our fishing skill when we showed up with those trout, "You boys been out ice fishing somewhere?!"

At that point I decided I'd stick with hunting...
Then there was the time my cousin and I went up to Red River tent camping and I managed to get my Jeep submerged in the middle of the river when we came down out of the mountains - it had been raining and I learned the hard way that "Hey, it doesn't look any deeper than before... " isn't always accurate...
Hmmm, come to think of it there are too many of those kind of stories, maybe I need to take up a different hobby... .
