We also full time in our RV (for over 20 years) so we want all the comforts in our home (just happens to have wheels) that we had in our fixed location home. We mostly have hook ups at night but sometimes dry camp using a generator a few hours in the AM and at night for cooking and entertainment before going to bed.
We also use the RV for business and while working in N. Orleans after Hurricane Katrina we ran the generator for 9 days 24/hours a day. Dry camping at its best! You just have to do what works for you.
