As far as I understand (I’m not english) from wiki page, tag caravans=yes/no is related only to trailers (AKA “roulottes”). In this case, there are no tags to define a camp site where only “campers” (AKA “campervans”) are allowed. There are many of them in Italy and several are simple parking places with some amenity, but cannot accomodate trailers nor tents.
How can I map them?
Which is the correct definition of “caravan”?
practical: like you said, a vehicle plus towed caravan can hardly accomodate in a 5-7 meter parking space
legal: a towed caravan, once stabilized, loses its moving status and become camping, which in Italy is forbidden outside caravan sites.
Note that in several countries even an overnight stop of a camper is illegal. Instead, in Italy you can: that’s why I think is important to differentiate tags for OSM.
Surprise, there are inconsistencies in the osm wiki.
This one makes more sense to me
"The caravan might be a trailer towed by another vehicle (ie travel trailer, camping trailer, popup camper), or a larger motorized vehicle (recreational vehicle (RV) or motorhome). "
which is from: Key:caravans - OpenStreetMap Wiki
I think we would find that ‘caravan’ is used in the wider sense most of the time
I would tag it as:
caravan=yes
motorhome=yes
trailer=no
maxlength= *
motorhome, based on van chassis, with its own interiors and exteriors
From a tagging point of view, campervans and motorhomes can usually access the same places and have the same legal status for parking or camping. I think applying same tagging (ie: “motorhome”) can be confusing. Should we go for motorhome=yes/no/only and campervan=yes/no/only?
Note: actually some barrier exist to block motorhomes VS campervans is some parkings (ie: supermarket ones with max height restrictors ), but they are up to property and not to traffic rules.
It’s a commonly used distinction in the US. A campervan is on a van chassis, less than 7 m, a motorhome can be huge, like a full size bus.
Often there is a legal distinction for an RV, it includes a toilet and shower. Many campervans do not have that.
A “camp site where only campervans are allowed” is tourism=caravan_site. That may sound weird, but it’s just a label - refer to the wiki to see what it really means. This includes things that look like “designated parking spaces for campers”, if overnight stay is explicitly allowed. If you want to avoid confusion, you could follow the advise here to add caravan=no and motorhome=yes. If I were traveling with a caravan, I wouldn’t trust I could use any caravan_site that did NOT have a caravan=yes tag (i.e. in Europe it feels like the default is no and people don’t add that tag often).
it’s admittedly a bit confusing as someone might be traveling with a caravan and think it applies to them while it actually refers to caravans rather than caravans…
