I saw one of these last year and the designing is really top notch very clever and the standard of workmanship is high Yes they are expensive but they are made invidually to order by a small maker, it impressed me! He has a waiting list of people waiting for them, or he did last year....
It is a very individual product, go have a look and see what you think.
They are made by Tabbert and are from Germany, I actually saw one in Norwich caravans waiting for a service, Looked so space age,so i had to make a note of it, to look up when i got home.
