Hi Lislou
Just something to think about ! If you like the idea of a seasonal pitch as your new to towing, the camping and caravan club have quite a good few sites all over the country with caravan storage on site, so you could store your van at a site you like if they have a vacancy it will save you looking for storage at home, then when you want to use your van book a pitch on your chosen site and the wardens will remove it from storage and pitch it for you .
You will have to erect the awning fill your water bottles plug in your electric cable ! But it could be less hassle to see if you like the caravaning way of life.
