I remember graduating from my driveway to the first FHU CG last year. I was really nervous getting it backed into the space. And then felt a bit clueless about the hook-ups - I almost didn't have enough water hose as that CG had their spouts way behind the back-in spaces.
We were less than 20 miles from home, but glad to be paying for the FHU for practice while we'd still be close to sources of supplies if we learned about anything we missed.
It was a blast the first time we walked around the park looking at everyone's rigs and then turning the corner and seeing our new-to-us TT sitting there ready to enjoy.
