Sitting in stationary traffic for several hours as the fuel gauge descends, only to eventually drive past an overheated camper van in time to join the next queue behind the next broken down camper van. Repeat around nine times between Stonehenge and Basingstoke, nearer 17 times around festival season and Bank Holidays.
Finding out that the apparent road on the map is actually designed for horse and cart, not camper van and combine harvester approaching one another. And those dry walls look amazing, but they make it even tighter.
The gusts of wind across the moor just as you're at the bit with the really big drop down into the leat.
Sitting in concrete car parks because camper vans couldn't access the nicer areas of the only campsite that accepted them. So waking up next to the toilets.
Where there isn't concrete, waking up to realise that you aren't going anywhere because it's rained and that slope is no longer a gentle incline/the AA can tow a car but haven't got anyone near enough with kit to pull a van out of the mud/sand.
Weight, height and wheelbase restrictions on bridges.
The cold. They are so cold. Except when it's hot and then they are the stinkiest, sweatiest oven.
Waking up cold in a tent means decamping to the car, putting the heating on and most likely heading for somewhere warm a hotel preferably. Not quite so easy with a camper van that's got to be packed up, disconnected and then driven off site.
The locals. Family with a normal car and a tent - no problem. Family with a camper van getting some shopping from Sainsburys - OMG THE TRAVELLERS ARE COMING.
Not being able to park up and go for a walk or shopping without somebody from the council pointing out that they do not allow overnight sleeping/camper vans are not allowed.
In order to prevent both of the above, height restrictions or outright bans. Or just not being able to fit in an enclosed car park at all.
Might not be an issue these days, but crawling up the hill hoping that the gearbox would take it in 2nd. And the noise inside.
Miscreants knowing that as it's a camper van, there may be some really expensive stuff inside/the parts are worth a lot and the owners aren't around. Worse ones seeing a single woman and kid outside the camper van (because they're far more visible/clearly on holiday compared to woman and kid getting into a car who could be locals or on a day trip).
Finding that instead of your nice, easy to handle car that doesn't cost too much to run, the other party decides that he needs that and you'll have to drive the van around.
Great when I was 17 and we all just wanted to spend the summer surfing. Not great in November or once there was a kid I preferred to not suffer hypothermia. And the ex morphing into a 'We're Campervan People' and refusing to go anywhere that didn't offer free parking for campervans or that wouldn't have been suitable, despite having a perfectly adequate car instead, wasn't exactly on my wishlist when staring at the skies as a teenager.
