This is DH and my last resort, we often sit back and think how we should just sell everything and buy a van (ideally mobile one...but a van either way) and be gypsies...would love it!!! (if i wasn't so attached to my stuff)
Enjoy your van =)
and all the best with the house building!!! never done it myself but a few friends have and they always have some story about delays or stuff not being as planned. Hope it goes smoothly as possible for you!!!
