Whether you drive an RV or tow a trailer/5th wheel there is a process you must go through to set up your home to be ready to use.
If you think you have problems parking your car you better start practicing parking your RV/trailer in a parking lot with few obstacles
You need to learn to back into a spot, turn tight corners, and watch your height for overhead obstacles.
Once you've managed to park it you will need to make sure it is level
You may have electric/hydraulic/or crank jacks
You will also need pads (1'x1' 3/4 plywood works great) so that your jacks do not get buried in sand/dirt/clay/other
You will also need a set of 1" pads (wood,rubber,plastic) to help raise your vehicle if the jacks travel is not enough to level the vehicle
Most places supply water if they don't they are "Dry". If you do not have a water storage tank, you will want a water hook-up
You will need at least your vehicle's length in "drinking water" water hose (not your typical garden hose). I would have extra for those hard to reach places
You will need a water filter to attach before it goes into your Vehicle's water system
You will need a water pressure regulator (most places crank up the pressure to supply large areas)
You will also need various plumbing fittings to hook up your hose from different angles
Most places have sewer. If your "site" does not have sewer, there is usually a communal "dump station" where you can dump before you leave the site
There are two types of sewer tanks
Grey: Sink waste
Black: Toilet waste
You will need "RV sewer" hoses to connect to the facility's sewer so that you can use your sink and toilets and drain (Dump) your sewage
You connect your sewer hoses to the drain
You monitor your use of water and dump when your tanks get full. We as a couple in "super conserve" mode can go 10 days without dumping, typically 5 days of regular use. Living/using an RV you instinctively start watching your water use.
You want to periodically pour Pinesol with about a gallon of water into your toilet while you drive to your next destination to keep your black tank clean
Most places have electric.
There are 3 types of electric hook-ups
110 Volts, 30 amp & 50 amp
Electrical power supply needs will depend on your appliances use
