The speed isn’t a big problem. It costs you an hour and a half on a trip to Scotland. So basically all day is still all day. As for wild camping – seems to be a bit of an unknown area legally as from what I can tell its governed by local byelaws.
But it does solve the two-van issue rather well. Swings and roundabouts.
Caravans are good if you’re the sort of person that pitches up for two weeks and doesn’t move the van in that time.
Not at all. We do single nights all the time. Never stayed anywhere for two weeks.
Also on the continent (particularly in France) there are lots of free or cheap Aire’s that take motorhomes but not caravans.
Unless that’s changed, there are still plenty of ones that take caravans because we stayed in aires all the time when I was a kid.
