Another historic Jem Via: The Vintagent
"The Rudge Caravan was introduced for the 1927 model range, further exploring uncharted territory for touring motorcycles. A complete outfit was offered, with Rudge 500cc ohv motorcycle and 'Semi-Sports' sidecar, plus the trailer, for £136.50. The Caravan itself was 7'3" (2.23m) long 4'10" (1.5m) wide, and 4'7" (1.4m) high. Inside were two small beds, a table, storage lockers, etc. Weight of the caravan was 285lbs, about the same as the solo motorcycle. It was recommended that cooking and washing occur outside of the trailer - cooking especially due to fire danger. A commercial version of the trailer was available, and were in use as late as 1944 delivering milk by the Coventry Co-op."
