In the UK Vanlife is a growing market, as well as those that just use Motorhomes and caravans for a holiday. 'Wild camping' (Boondocking) as it's known here is causing quite a stir as it gets more and more popular and local councils are introducing height barriers and bans on parking overnight in response to local complaints. New websites are cropping up with free or cheap overnight options where others can add to the data base. (Park4night/Searchforsites etc)The problem is the more these spots are shared on-line the more popular they become and that creates a problem with the local residents and then the councils react with enforcement policies. We live near a quiet beach area and for as many years as I can remember you would have 3 or 4 campers down there stay the night. Then came the 'power' of sharing your great find on the Internet and suddnely there were campervans nose to tail for 2 miles along the seafront and yep, the local dog walkers and residents who couldn't park started to complain and now its a no go zone for any campers between 8pm and 8am. Sometimes, oversharing is like shooting yourself in the foot !
I have heard of campers letting like minded people use their driveway and even swapping driveways for a week or two for a change of location and providing electric and water hook ups. If it does take off in a big way, I'm pretty sure it will soon be clamped down on by the local councils.
One idea that is taking off is for pubs to boost trade by offering a free place to park in exchange for simply buying a round of drinks or some ask that you dine in the pub.
