We have just had an unexpected stay in our van for a week, due to contractors wanting to carry out our new kitchen, due to wife's medical conditions and the dust ,noise and no water I had a word with the owner where I keep the van about staying there. No problem he said move van out of lockup and put in field on hardstanding, used two leads and hooked up to electric in lockup also had water via his outside tap.
Worst week weather wise but van was great nice and warm nothing went wrong so nice little break.
