My wife and I wanted to take our bikes with us when camping, but we had no good way to carry them. It’s a little crude looking but it works and it didn’t cost that much, if you don’t count the time it took me to build it.
We finally broke down and purchased generators for our Airstream. Even though we have a solar panel on the roof that usually keeps our batteries topped off, we sometimes need a little more power for some situations when boondocking/dry camping. We don’t like the sound of generators in campgrounds, but there are times when generator power is necessary, like it or not.
It’s really quite easy. I’ve done it. Put your awning out in the rain and don’t have one end of it a lot lower than the other end. When the awning fills up with water, the awning supports will snap and the pieces attached to the spring mechanism will spin around and thrash the aluminum on the side of your trailer. It sounds like your tailer has been hit by lightning and it shakes the heck out everything. Quite exhilarating, expensive and is best experienced on the second day of your vacation. I know.
