See the motorhome technical book for
the classification of your motorhome.
The classifications are as follows:
Grade 1
A motorhome with an average thermal
transmittance (u) that does not exceed
1.7w/(m2k).
Grade 2
A motorhome with an average thermal
transmittance (u) that does not exceed
1.7w/(m2k) and which can achieve an average
temperature difference of at least 20k between
inside and outside temperatures when the
outside temperature is 0°C.
Grade 3
A motorhome with an average thermal
transmittance (u) that does not exceed
1.2w/(m2k) and which can achieve an average
temperature difference of at least 35k between
inside and outside temperatures when the
outside temperature is -15°C.
