A buddy on another forum had this to report. Interesting......
"Just back from a week of camping in Austria and the Munich, Germany area, and I have to say that it was great fun as well as educational. Camping is very popular there, and you'll see trailers, as well as small RVs, on the road everywhere. The trailers average out at about 20 feet or so, mostly single axle
, and pulled by a small car or small SUV. A VW Toureg is a large tow vehicle there. We saw exactly one pickup truck, and it was pulling a small 5th wheel - the only one of those we saw, as well. You just don't see the mega bus campers or very large trailers. Although semi trucks travel the secondary roads, you'd be challenged pulling a wide body Airstream. There's no room for error, and the Austrian and German roads have small wooden posts just off of the paved surface - no shoulder - to keep you honest. The roundabouts you'll go around in every town are another difference in the driving experience. The Autobahns are the quickest way between two points, but there are plenty of scenic twisties in the Alps regions.
A popular layout for a Euro campground is to have the campers nose to tail along the roads, and you park your car alongside. You back the trailer partially into the space, disconnect, and finish pushing it into place by hand. All of the trailers have handles built into the body at the corners, and a nose wheel at the front jack. A standard practice is to extend the living space by attaching a three sided room to the trailer."
