EU Directive 1230/2012 applies at a European level for cal-
culating the masses and resultant additional loads for mobile
homes. The terms and basis used for calculations are
explained below.
1. Technically permissible overall mass
Information regarding the technically permissible maximum
weight is based on Hobby Wohnwagenwerk's specification in
cooperation with the manufacturers of the previous construc-
tion stages (Fiat). This mass takes into account the specific
operating conditions that are based on the model of the mobi-
le home and its performance, including such factors as mate-
rial strength, load-carrying capacity of the axles and tyres, etc.
For safety reasons, this mass must never be exceeded!
2. Mass when the vehicle is ready to start
The mass when ready to drive is equal to the weight of the em-
pty vehicle including lubricants, tools, spare tyre (or tyre repair
kit), petrol (90 %), ancillary battery, all of the standard equipment
installed by the factory as well as 75 kg for the driver. In additi-
on, the masses for the fresh water and gas storage containers,
which have been filled to 10 % (fresh water) and 100 % (gas) of
their total capacity, must be added. The masses are calculated in
detail as follows:
