To complete this list:
capacity:motorhome  32
capacity:motorhomes 0

The thing about caravan and caravans is a mess. Both keys actually exist...
- 'caravan' refers to the vehicle in form of a trailer and whether it is 
allowed to access some highway / area
- 'caravans' refers to either trailers or full motorhomes and only 
applies to camp_sites.

So, capacity:caravan should be used on parking lots that have spaces for 
cars with trailers, while capacity:caravans should be used on camp_sites 
that accomodate either caravan trailers or motorhomes, but there is no 
distinction possible between both kinds of vehicles.

As a result this is a fully valid tagging:

amenity = camp_site
caravan = no
capacity:caravans = 10

That would be a camp site you can enter with a motorhome, but not with a 
trailer.
