<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">home on wheels</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for caravan that I've seen before include "Towable home" , "Group of desert travellers" , "Motor-home" , "Towed accommodation" , "Home on wheels" .)
