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specicationin
cooperation with the manufacturers of the previous construc-
tionstages(Fiat).This mass takesintoaccountthe specic
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 addition,
the masses for the fresh water and gas storage containers, which
havebeenlledto100%oftheirtotalcapacity,mustbeadded.
The masses are calculated in detail as follows:
3.3.2 Denition of masses for mobile homes
If you are not sure whether or not you have overloaded the
vehicle, you should have it weighed at a public weighing
facility.
The maximum axle loads as well as the technically permis-
sible overall mass entered in the vehicle‘s documents may
not be exceeded
Overloading can cause the tyres to break down or even
burst! This increases the danger that you may lose control
of the vehicle. Therefore, you endanger yourself and other
road users.
