Caravan has been static on a farm in Surrey.
I more or less gave up using an inverter as it draws too much current.
A long time ago I completed the heat exchanging fan/ ventilation unit. This is functional and useful in the heat (instead of leaving windows open), but I have not found it heat exchanges very effectively so am only using it sparingly.
I beefed up the door, so it is much better insulated, also painted nicely.
Tidied up some of the woodworking around the windows, but this is not quite finished.
I have regularly been using a rocket stove, and this is pretty good. It took me a while to get the fuel amount right and I have been using kindling and natural firelighters (based on wax soak), some harvested wood, but it really takes a long time to dry out without heating it. I confess to not cooking much, just heating food and boiling water.
The video below was recorded about 6 months ago and is a detailed update.
I am quite happy with the replacement spats I made for the wheel arches. The original plastic ones were split and looked awful. I tried to find replacements online, but sny available were very manufacturer specific (not available for my old thing) and ridiculous prices. I just used pine mouldings from B&Q.
Unfortunately I had a solar panel fail. I was an idiot, and it took me a long time to realise even though I though I was pretty good at electrics. The voltage was present from the panel, but no current was drawn. I noticed that the battery was failing to charge and over the autumn/ winter was continually using the mains battery charger to get power. I mistakenly thought the battery was a dud, and spent 70 pounds on a replacement only to observe the same thing (after I had taken it to the dump...) I then suspected the solar controller, ditto. I have 2 of these now. Then I tried to troubleshoot the panel to no avail (Titan Solar were useless at responding to queries), the replacement one (from another supplier) has been working just fine.
I have learnt that the new ultrathin flexible solar panels are not so good as they appear, I still intend to fix it, but it is REALLY hard to get to the internal components as they are bonded.
I had a small leak to deal with around a window about a year ago, but I have been really happy that all the seals have held and all the interior and exterior decoration still looks very good.
