This is an excellent "blog" and both my wife and I have enjoyed reading it. Last year we also did a six week "grand tour" of Germany, starting at Lake Constance(Der Bodensee) then up to Thuringia, on to Dresden, back to the Hartz mountains, and down to the Rhine at Rudesheim. If I was competant enough with my laptop I would produce a similar type of travellogue. I would agree with you that it is a shame that more British caravanners do not explore Germany. It is a lovely country with very generous people.
Perhaps it is because most people of our generation (those born during or soon after World War II) learnt French at school and so have an affinity with France.
Having said that, this year we returned in June from a six week tour of France. However my wife has hinted that a tour of the Baltic coast of Germany may be something to consider for next year! This remains to be seen.
Regarding your comments about the bombing of German cities during the war, I would suggest that this was a political decision, made for what at the time were valid reasons, and the 55,000 RAF bomber crew members who died were obeying their political masters orders. The sad thing is that they were ordered to continue with the campaign when Germant was a beaten country in the spring of 1945. With the benefit of hindsight, I hope we would now think differently.
As a final point I would comment that the rebuilding of German towns and cities after the war was done on a human scale. Unlike our rebuilding projects of the same time which were dominated by the Stallinist school of architecture, that is massive concrete blocks which are now being demolished.
