Hi Simon, buickanddeere gave a good over view on how the absorbsion refrigerators work. You will need to add a fresh intake chimney, approx 6" x 24" x 6" that takes in outside fresh air for burner combustion and condensor coil cooling and a supplys a exhaust thru the roof of combustion gasses. Look at Camping World or on-line RV Parts for RV refrigerators as they run about $1200 for a 12cft. They don"t need perfect level, about 5º out of level is fine. Something new in the past couple years. They still make the Sevrel refer"s that are about $1800 for a 14cft ? I lost all my bookmarks so I can"t refference them. The RV units are a much better buy. You will also need a 12vdc source. A couple golf cart Trojan T-105 deep cycle batterys (about $70eh) with a solar PV pannel of 64w (about $300eh) and a charge controller (about $45) for a complete solar orperation. This will also give you great lites for the cabin. I also use a 12vdc RV water pump (about $55) and a 6gal LP DSI water heater. Use a 2kw genset for cloths washing with a LP dryer. Stay away form invertor use. Very expensive when most everything can be had in 12vdc for a reasonable cost or ran on a genset cheaper. Hard to beat the cost RV parts for remote installs. T_Bone
