TECHNICAL SPECIFICATION

TECHNICAL DATA

Base Vehicle Data

For all matters relating to the base vehicle,
and particularly tyre pressures, refer to the
base vehicle instruction book or if in doubt
consult your local base vehicle commercial
dealer.

Weights, Dimensions and Capacities

Before using your Auto-Sleeper you should
be fully conversant with all matters relating to
weights. The following definitions should be
fully understood and then related to the
tabulated base vehicle weight data.

Weights

Details of vehicle weights are found below,
and are presented in the manner prescribed
in the European Union Regulation 1230/
2012.

Take care to ensure that heavy loads are
stored low down in bed boxes and low
cupboards, and distribute weight evenly side
to side as far as possible.

Note 1:

Please take care to ensure that you

have allowed for the masses of all items you
intend to carry in the motor caravan, e.g.
passengers, optional equipment, essential
habitation equipment and personal effects
such as clothing, food, pets, bicycles,
sailboards, sports equipment, etc.

Note 2:

Warning - Under no circumstances

should the maximum technically permissible
laden mass of this motor caravan, or its
individual axles, be exceeded.

Note 3:

The Mass in Running Order contains

provision for the mass of liquids, gas etc (see
definition). Part of this provision can be
utilised as additional payload if, for example,
you wish to travel with water tanks empty or
with no gas cylinders.

DEFINITIONS

Maximum Technically Permissible Laden
Mass (MTPLM)

The Maximum Technically Permissible Laden
Mass is a figure given by the manufacturer of
the base vehicle. It is the combined maximum
permitted weight of the vehicle and all of its
contents, both inside and out. The MTPLM is
unaffected by the Auto-Sleeper conversion.

Mass in Running Order (MRO)

The Mass in Running Order is defined as the
mass of the vehicle equipped to the
manufacturer’s standard specification and
including the following:
•

Driver (assumed to be 75 kg, 11st 12lb)

•

Fuel tank - 90% full

•

Mains electricity connection cable

Note:

The MRO assumes that the freshwater

tank is empty. If you travel with water in the
freshwater tank then the User Payload will
reduce accordingly.

All other optional equipment whether on the
base vehicle or part of the conversion is
excluded from the mass in running order.

Mass of the User Payload

The Mass of the User Payload is the
difference between the MPTLM and the MRO.
It is the vehicle’s carrying capacity for
everything placed in or on it, including the
passengers (but excluding the driver who is
already included in the MRO).

Everything listed in italics below must be
subtracted from the payload.

Mass of the Conventional Load

The Conventional Load is the mass of the
passengers carried and must be subtracted
from the payload. The “EU standard person”
weighs 75kg (11st 12lb). The user should
adjust the figure according to the mass and
number of passengers carried. Motorhome
Manufacturers designate passenger seats as
being suitable for travelling, and provide seat
belts accordingly. Multiplying the weight of the
passengers by the number of passengers
gives the Conventional Load. Please note that
a driver (at 75kg, 11st 12lb) is included in the
MRO.
