That was very good advice, but...., let me offer a few minimal cost "gadgets" that are almost essential, particularly for rustic, dry camping:
Water Bandit- lets you hook up to almost any spigot, threads or not to fill your tank: https://www.amazon.com/Camco-22484-W...s%2C191&sr=8-6
15A to 30A power adapter, lets you plug in to available 15A recepticle: https://www.amazon.com/Epicord-Dogbo...NsaWNrPXRydWU=
Leveling ramps. This is a ramp and another type is interlocking blocks. I have found that the ramp works well 95% of the time. Place in back of your low side wheels and back up, then put a chock in front and back of the front wheel once you get to the right height.
For RV park camping with full hookups, a longer waste hose with leveling supports. This page has examples of both: https://www.amazon.com/s?crid=194W7U...s%3Dautomotive
