Solar power would be a a real bonus charging you leisure and vehicle battery. Having addresses of Laundresses is a good thing to have on ones lists. So far as parking up is concerned one would need to know best places to be able to do that and where else to go if your favourite is taken. My vehicles have been 4x4 or have All Wheel Drive for many many years and have camped off road for many years completely out of view and attention, so a VW with 4Motion might be worth considering at least it would allow more options if afordable. One of the best investments that we have bought was a Wallas Hot Plate with 2 cooking hot plates with heating and complete with a blowing fan. Mine was run on Paraffin but most if not all now run on Diesel now. They are comparatively expensive to buy but the double role hot plate and heater all in one had been a huge bonus. They use very little diesel and 12v requirements are very low drain so can be left running all day quite cheaply and heat the van at the same time because they have a vent or small chimney the fumes are vented outside. This also keeps the inside of the van warm, dry and fume free because it is vented and also no humidity and condensation is let loose into the living area, so many bonuses in having that sort of device. Heating, cooking, making a cuppa, condensation free, cheep to run, low battery drain, and reliable, no naked flame. they are popular on Boats because they do not run gas so no risk of explosion CO poisoning. They have a lid with a thermo fan, if the hotplate is hot when closing a small fan blows hot air around the vehicle, brilliant.
