We went on a trip this weekend 5 hours from home. When we were about 4 hours away we stopped at a gas station and I was checking out the camper while we were stopped. That is when it hit me, I had forgotten to remove the crank handle used to raise the top. It had fallen off somewhere down the road. Luckily our crank has the square metal tube sticking out that the crank handle slide into. Within a mile from leaving the gas station, I saw an Ace Hardware. I carry a Crescent wrench in my tool bag, but it was too small to fit on the 1" square tube so I bought a large wrench at the Ace Hardware. It took about 10 minutes to raise the top but at least we could get it open. I ordered a new crank handle while I was at the campground and it should arrive in a week or so. It was just a matter of time that I forgot to take the handle off. I will keep the large Crescent wrench in my tool bag from now on, just in case.
