I’ve found some british definitions for non-trailers recreational vehicles. To sum it up, the class
Recreational vehicle (RV) is composed by:

  • trailer (AKA roulotte), towed
  • campervan, based on van, with modified interior
  • 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.
