Thanks for the kind words!
We are going on a trip this weekend to see how everything now works. This week the temperature here just jumped sky high, so I doubt there will be any need for the heater this weekend.
Our experience with the vehicle and the 'box' so far is that is is just what we need to live comfortably when on our outings. There is room enough for the two of us, but there is not enough hight to stand upright. The interior hight is a little low at 167cm. The wife and I are both 175cm tall. The interior with is 182cm and the length is 244cm.
The Dickinson heater: Our first thought was to use a diesel heater. The Dickinson diesel heaters have a nice glass door, and can be had with a cooking top. However, in our cabin (45 sq meters) we have a kerosene heater, and there is always some smell when using that. In the small space in our camper we thought that could be a problem. In addition we would have to install a small day-tank and a fuel pump, plus some piping when installing such a heater. The solid fuel heater is a simpler installation, the smell of burning wood is nicer, and firewood can be found everywhere around where we live. It also gives some redundancy as we still have the Webasto diesel heater too. The Dickinson does not require any electricity at all, so if we were to be stationary for any length of time, that is a big plus.
The plan was to have the map on the front wall again. The problem is that the map is glued to a 3mm thick plate. This is just to thick to fit now. If we mount it, we wouldn't be able to fully open the lids under the sofa mattresses. I have to sort this out, as we would very much like to have the map installed again too.
Thanks!
