Hiya Beverley, everyone has their routine for setting up, breaking camp, is just the reverse. Excellent advice from Michael, read all you can read before doing anything, then, follow the advice given. To make life easy, pick a site that is close to home first and with level pitches. Here is a quick run down of what I do when arriving on site.
Get the legs down first, use a cheap spirit level that you can keep in your van to make sure everything is reasonably level.
Go inside the van and make sure everything is in the off position, taps in the bathroom and kitchen, the drain tap (yellow) that is next to your water heater (should be horizontal, not upright), water pump, and all heating and water heater controls are off.
Outside, you can connect your 240v hookup cable to the van and then to the site electricity post. Go back in the van and check that it's working.
Place your waste container next to the waste outlets and use a couple of pieces of tubing to connect the two.
Fetch your water, plug in your water pump and put the pump into the water carrier.
Turn your pump on and you will hear it taking in water. Open the hot water tap, this allows the water heater to fill and then make sure you have running water from the hot and cold taps. Turn on your water heater.
Go to the locker that contains your gas cylinder and connect it to the gas regulator. Chances are it will be a propane regulator so make sure you have the correct gas, turn it on. When using the gas appliances remember it will take a few attempts for the gas to bleed through the system, so you may need to restart things like your hot water system a few times.
You are now connected to the services; you have water in your taps, electricity in your sockets, gas in your hob and hopefully cold beer in the fridge.
I would suggest running everything on mains supply first, and then try using gas when you are more familiar.
Then comes the luxury items, the awning, the TV, the wind breaks etc.
It all seems like a lot of work to do, and this is the simplified version, but you can connect up to the services in less than 20 mins, and when you both get used to it, it becomes a doddle. Don't be afraid to ask another caravaner for help, it gives us an excuse to look over another van and breaks the ice. You are going to have fun discovering your van and what it can do; you will have even more fun taking those extra holidays you can now fit in, welcome to touring. ;o)
