Preparing For The Road - Bailey pproach SE Owner's Manual

YOUR MOTORHOME
(Weights Explained)
Mass in Running Order (MRO)
This refers to the weight of your motorhome
as it leaves the factory complete with its
standard fixtures and fittings.
• 90% of automotive fuel
• Driver (at 75 Kg, 11st 2lb)
• The LPG cylinders 90% full
• The fresh water tank 90% full
• The water heater 90% full
• The Waste water tank empty
• The toilet flushing tank, full.
• The toilet system holding tank, empty.
Any additional passengers/ equipment
are excluded from the MRO and need
to be taken into account when calculating
your available payload.
Maximum Technically Permissible Laden
Mass (MTPLM)
The maximum weight of the vehicle when it is
fully laden for use on the road. See your
Service manual for exact specification.
User Payload (Sometimes referred to as
GVW)
The load Margin (payload), is the difference
between the Mass in Running Order (MRO)
and the Maximum Technically Permissible
Laden Mass (MTPLM). This shows the
maximum weight that can be loaded into your
motorhome; it covers items such as optional
extras, clothing, food, crockery, cutlery,
bedding etc. Please see your Service
Manual for exact payload figures.
Please take care to ensure that you have
allowed for the masses of all items you intend
to carry in the motorhome e.g. passenger,
optional equipment, essential habitation
equipment as well as your personnel effects
such as clothing, food, pets, bicycles etc.
Your passenger's weight should also be
taken into consideration when loading your
vehicle. Please refer to your MRO and
MTPLM.

PREPARING FOR THE ROAD

You may wish to allocate the user payload to
suit your own use. For example, to increase
the available payload, the water system may
be emptied. If the vehicle is not being used
for camping, the gas cylinders can be left at
home to increase the mass available for
other items.
Gross Train Mass (Sometimes referred to
as GTW)
If you are towing a trailer with your Bailey
motorhome the gross train mass is the
MTPLM of the towing vehicle, the trailer and
the mass of every item carried., the GTM is
specified by the base vehicle manufacturer
(AL-KO) and is unaffected by the Bailey
Conversion. Please check your driving
licence to ensure you are allowed to drive a
vehicle combination at this weight.
Maximum Braked Trailer Mass (MBTM)
This is the maximum allowable weight of the
trailer together with its load, provided the
trailer has a braking system, which complies
with the local Construction and Use
Regulations. The MBTM is given by the base
vehicle manufacturer (AL-KO) and is
unaffected by the Bailey conversion.
Nose Weight:
The static mass of the trailer towing device
on the rear of the towing vehicle
i. When measuring nose weight it is
important that the trailer is loaded.
ii. The trailer is intended to be towed slightly
nose heavy. The nose weight can be
adjusted by redistribution of the load.
The nose weight should be
approximately 7% of the actual laden
weight (but not greater than the hitch
capacity) and at the same time suit the
motorhome requirements.
Axle Loads
The individual axles also have upper limits.
The sum of the two axle upper limit usually
exceeds the overall vehicle MTPLM, but this
does not mean you can load each axle to its
maximum, because doing so would exceed
the overall MTPLM of the whole vehicle.
