We had bought a cheap second-hand m-liner carthago camper in Germany. This with the intention to renovate it. So all old camper electronics out. Repair damage to the motorhome. Old solar panels from the camper off. For this a new installation of Victron with 100 Watt solar panels mounted in front of it. A new Dometic absorption refrigerator with a capacity of 177 liters with freezer compartment with 35 liters. Conversion from single beds to a large bed in the motorhome. A drive-in system for the scooter in the sawiko camper. Extra sockets with USB and 12 volts. development of aggregate. Expansion of LPG installation for a motorhome. Dent and spray. Installation of a particulate filter for the Mercedes sprinter engine from 2001. Repairing the camper toilet and drain tank. New gas installation with crash sensor and new gas pipe in the camper. Major service for the Mercedes sprinter engine. New brake lines and repair of many minor issues. New sealant low in the front seam. A new gas oven for the camper. A new alarm system with gas detector and alarm. A new mio scooter for the camper. LED lighting for the camper everywhere. And many other things. Actually too much to mention what has been renovated in the camper. As a result, the inside of the camper has been well refurbished. A camper renovation company where this business is done is located in Koblenz, and is called FK-Reisemobilservice. Refurbishing the camper cheaply has not been successful. But for that we got a nice old camper back. Pimping the camper was successful. Buying and refurbishing an old camper took us half a year. But modernizing the camper has paid off for us. The cost of a second-hand motorhome is therefore very dependent on various factors.
