Right in time for the camping season, mobile home manufacturer Hymer presents its new interpretation of a classic: the B Class DynamicLine. Don't confuse it with the B class from Mercedes Benz; the Hymer has been around longer.The first one came off the assembly line on a Mercedes chassis in 1981. Since 1987, it's been built on a Fiat chassis. The newest generation has drastically lost pounds using light-weight materials. It has a shower and a toilet, and still weighs in at under 3.5 tons. And so you can drive it in Europe with a standard passenger car driver's license.
