Courtesy when neighbor is hooking up.

[Roger C H]

A tip from the Good Sam site:

"When you finish hooking up everything, literally stand up and look – carefully look – at each connection just to ensure it is good and complete.

This 15-second safety inspection could save your vehicle. A common campground courtesy rule is not to talk with folks while they are hooking up towed vehicles. Some incomplete tow hookups are a result of you being interrupted by someone or something during the hookup procedure. For example, the person in the next campsite says “goodbye,” and you look up to acknowledge the comment, and forget to attach something. It happens. The visual double-check helps prevent incomplete hookups."

So the courtesy you can do is wait until he is hooked to talk to him.

It is a good point to check the whole rig over (including hitch/hookups) before pulling out. And to be able to say "I can't chat right now, sorry."

I usually stop on the road out of the campground and double check.

Hook up.
Pull forward a trailer length and walk around to see what had rolled underneath. Check chains, hitch and lights.
