As requested extra caravan pictures and info.
The small table can drop down to help form base for lower bed, and frame hidden below window pulls up and out to form upper 'bunk bed'.
In the photo looking along the interior to the main seating area, the slim cupboard on the right of the picture, houses the folding table, that links to the drawer unit at the end to form another dining/leisure table. This seating area can be used to form 2 single beds or bridged over to make one large sleeping area for 3.
The built in heater is a Carver 1800 gas heater, or you can use the electric fan heater (included) which helps to save the gas.
