We have a Volkswagen Caravelle as a day-camper and all-round family lugger ,and a MINI. My wife has a new job and will have to visit rural sites in the Lowlands and Highlands all year round. We need it to be a commuter and a family load hauler (including a dog) and to tow boats. We'd like to at least make a nod towards something a bit more environmentally acceptable but would have range anxiety about electric as the transport routes include B-roads and next to no dedicated road service stations. We live eight miles from the nearest town and have to cart our kids around in the evening too. What type and model would you recommend for a £17-£22K budget.
