Im glad you asked that Daz
My solar install was a great success , my battery has not left the van since 15th Jan 2018 , so soon to be a year without it seeing the light of day or a mains charger , I dont miss lugging that out every night !
Plus by going self diesel I will actually save weight , full bottle , boiler , and plumbing comes to around 40kg , my planned system wont be close to that .
