Under the sink you will find silverware and utensils. The cabinet above the sink has cups, plates, bowels, cutting boards, table mats, and hot pads. The wooden sink cover is not a cutting board and can be placed under the sink or wherever convenient when not in use.
The Fridge can take several hours to cool and is not the same kind of fridge you would find in your house. Initially, only put items that are already cold to not delay the cooling process. Ice packs can help cool it down as will plugging it in the night before you leave and turning the propane on. (Remember to turn off the propane when starting your drive)
