living in a caravan to mitigate sensitivities, stop being around people?

If you look at the top article, seems this is one Autistic man who's taken up this lifestyle.

I think there's a 24 hour gym chain in the UK, just a thought. You could join them and park in a supermarket car park near wherever they have an outlet and use them for showers.

Supermarkets have time limits on their car parks - it's not easy finding a secure parking place for a van - the smaller the vehicle, the easier it is - but obviously more cramped inside.

I have 2 friends trying to do this at the moment - one has built a 'metal tent' from an executive Toyota Hiace - it's quite small and low so he can get into car parks with height barriers but that makes it little more than a bed on wheels.   He fitted a diesel heater and he can cook with the door open.   He uses it to get away for the weekend - he and his wife say it's camping without the wind flattening your tent.   (he's undiagnosed aspie)

The second is building a converted horse-box on a Renault chassis - it will have a rudimentary shower and toilet but it's a massive amount of work to get it built - I don't know if he'll ever finish it - I hope he does for his own satisfaction and wellbeing.   (He's a very diagnosed aspie but has motivational problems so progress has long stops when he can't function.)

That's a good plan with the elevation! What's your living situation like right now? What's the issue specifically you're having?

in the summer, you need to go up in elevation... so big mountains. think rockies or sierras, or actually various other ones.... for every 1000 feet in elevation, temp goes down 5 deg F... so at 7000 feet, you go down 35 deg F..... 7000 feet elev is reasonably common..... i would never go to humid areas.................unpleasant. many find being up in the mountains really nice and gorgeous.

UK is very cold and wet - much more the further North you go - we don't have many 'nice' days to be comfortable in a van.

US has a bit of everything - but really only 2 seasons - Summer and Winter - the Northern states are Mosquitoes or 6 feet of snow   

Southern States tend to be hot and humid or hotter and more humid  

That's why total insulation is the most important detail.

That's a clever idea making the van look like it's used by drain-clearance workers. Thieves usually target attractive vehicles.

The climate is pretty consistent throughout the UK. We're like the equivalent of one American state, whereas you guys have lots of different climates. I still have seen Americans claim that it's hot anywhere there in a van in the summer, though. Not sure what to believe on that.

Yes - you're right - I was under the  impression that they were UK based.

It is much easier in the US - I think Walmart pledged to allow van-lifers to spend a night in their car parks if they need to.

Some of the bigger issues are getting fresh water and safely dumping of waste water and toilet waste.

A big solar panel setup on the van roof obviously identifies someone living in a van so a conformal panel is less efficient but less obtrusive.

Having the ability to have outside space makes the van more versatile.

Some people put fake livery on their van to put off potential thieves - things like a couple of filthy hi-vis on the front seat backs and maybe labelling the van as drain-clearance specialists or as a charity church vehicle.  

The big problem is noise / light emanating from the vehicle in the dark of night - it's good to just be invisible to everyone.
