As others, I rarely go to full hookup places. The few times I have, I will always hook up the power, but nothing else. With doing more sightseeing trips at national parks, etc, I will often break up the first and last day's drive with an overnight stay at a full hookup RV park, then dry camp at the national park. I may do a full hookup night midtrip if I have multiple destinations so I can recharge batteries, etc.
I use the water out of my tank and will only fill if I am midtrip and know I will need more water than the tank can hold AND the water at the park is decent tasting.
I only dump if there is enough to dump by the time I am ready to leave.
Why do all that extra setup and takedown if it's not needed?
