[Tagging] caravans en-de inconsistency

[Niels Elgaard Larsen]

In the wiki EN:Key:caravans can mean either a camping trailer
or a motorhome.

But in German, DE:Key:caravans only means a camping trailer (de:
wohnwagen)

The result is that there are 222 objects tagged with: 

  tourism=caravan_site
  caravans=no


Some even with:

  tourism=caravan_site
  capacity:caravans=48
  caravans=no

Some of them in other countries than Germany.
I find this very confusing.

Wikipedia agrees with the Germans on the caravans key.
And on the wiki for Key:access, "caravan" is listen under Non-motorized
vehicles.
But then "tourism=caravan_site" makes little sense for motorhome sites
(de: stellplatz). "motorhome_site" or "rv_site" would have been better.

I guess it would work to tag motorhome stopovers, that does not
accomodate trailers with:

  tourism=caravan_site
  caravans=no
  motorhome=yes

Can we at least agree on whether caravans include motor_homes and make
the English and German wiki agree on that?
