No failure.... you passed with flying colors. You managed to back in your new rig and get setup correctly despite interruptions. And you didn't lose your temper. It is all good. They were trying to be nice, a bit off on their timing but they were trying to be nice showing interest in your beautiful new rig.
If it makes you feel any better, my maiden voyage as a newbie resulted in the camp host parking my tt for me. We had no hot water because I didn't know how to dewinterize the rig and was afraid to ask. DD locked all of us out of the bathroom and DH had to disassemble the lock to reopen it for use. Our second trip got the tt dewinterize but not without some comedy first. If you ever want some real entertainment, read these threads:
