Ha! I just knew this one would stir up a hornets nest.
Yeah, I know, everyone is different. I've never figured out thwe ones who have a nice big unit with a fully functioning shower & head who go trotting off, sometimes in the cold towels etc. in hand, to use the CG. Facilities. My shower stall is a shower stall, not a storeroom, though that is where the clothes hamper goes.
Eight years & literally hundreds of different CGs & we have yet to use a CG shower. Using a CG restroom is almost as rare.
Get water from somewhere once a week otherwise nope, we don't bother hook it up.
As a rule don't ask for & don't hook up to the sewer either. Make a dump visit somwehere every 4 days or so.
We know how to reverse so never ask for a pull through. Most of the time we would be happy with a tent site, if only it were long enough & maybe had 30A though we know how to survive on 20A using careful power management.
The CG owner I chatted with said that he would love to charge more for tenters & complained about how often they trashed his bathrooms. No small expense in labour daily to clean up after them.
