I can see no way one can spend that much time setting up and then returning to travel.
If I'm overnighting in a park I pull into the site, engage the jacks to level, walk outside and check the shorepower and connection and plug in. Hook up a hose for water and that just can't take over 10 to 15 minutes top. I never hook up the sewer for an overnight stay.
Hooking up the sewer is another 3 to 5 minutes, I use a sewer solution setup which is much faster than a stinky slinky. But even the slinky is not a big deal unless you insist on putting the little tressel to hold it off the ground. Going back to travel is even faster, 10 minutes tops. That said, I'm not all that agile on my feet and so others can do the same much quicker than I.
Now if you spending days in a site, the amount of stuff you pull out for comfort will add to the time. Lawn chairs, awning lights, leds for the ground, patio cover, folding table, bar-b-q, propane bottle, bikes, lighted palm trees, potted plants all take a lot of time and many feel that they need all of those homey things for their experience...after 10 years of fulltime, I have a bar-b-q, ground cloth, two lawn chairs.
