When your region is set to United Kingdom (in More -> Settings -> Region & Units), loadmate uses UK towing terms throughout the app. The labels you see on each field match the words on your vehicle plate, handbook, trailer plate, and caravan documents, so you can copy figures across without translating them in your head.

​
Common terms

These are the UK terms loadmate uses for the main weights and ratings. Each one maps to a figure you already have on a document or plate.
  • Maximum Authorised Mass (MAM): the laden weight limit for your tow car. It is the figure you check your loaded weight against.
  • Gross Train Weight (GTW): the combined limit for the tow car and caravan together when both are laden.
  • Maximum Technically Permissible Laden Mass (MTPLM): the laden weight limit for your trailer or caravan.
  • Mass in Running Order (MiRO): the trailer or caravan empty weight, used as the baseline before you add loads.
  • Nose Weight: the downward load the coupling puts on the tow ball. This is the single most safety-relevant figure to get right.
A few supporting terms appear on the same screens:
  • Kerbweight is the empty weight of the tow car.
  • Max Towing Limit is the towing capacity of the tow car.
  • Maximum Permitted Noseweight is the limit your tow car and towbar can carry at the coupling.
  • The trailer is called a caravan, the tow vehicle is the tow car, and the place you weigh is the weighbridge.
Coupling load is named differently in each region. In the UK it is nose weight; in Australia it is tow ball mass (TBM); in the United States it is tongue weight. loadmate shows the UK term when your region is United Kingdom.
Weights are shown in kg and lengths in mm, matching what you read off UK plates and documents.

​
Common mix-ups

  • Do not confuse MAM with MTPLM. MAM is the tow car loaded limit. MTPLM is the caravan or trailer loaded limit.
  • Do not use MiRO as the loaded limit. MiRO is the empty or running-order mass before your added loads.
  • Do not treat nose weight as the full caravan weight. It is only the downward load at the coupling.
  • Do not use a driving-licence towing rule as a replacement for the plate value. The app needs the rating printed for the vehicle or caravan.

​
Where to find ratings

Each UK term comes from a source you can read directly. Use these when you set up your rig or check the values loadmate carries.
  • MAM, Kerbweight, and Max Towing Limit: the tow car’s VIN or chassis plate and the handbook.
  • Maximum Permitted Noseweight: the towbar plate or the towbar fitting instructions.
  • MTPLM and MiRO: the caravan or trailer plate and the caravan documents.
  • Measured nose weight: a separate reading taken with a nose weight gauge, or a weighbridge ticket.
When you add or edit a vehicle or trailer, enter these figures from the plate rather than from memory. See Add a tow vehicle and Add a trailer for where each field sits in the setup flow.
If a plate figure and the handbook disagree, enter the plate value. The plate is the figure enforcement checks against.

​
Use this with source documents

loadmate compares the figures you enter against the limits on your plates and tells you how much margin you have left. It works best when the number on screen matches the plate, handbook, caravan document, or weighbridge ticket in front of you. The Driver and Vehicle Standards Agency (DVSA) sets and enforces the rules these figures relate to. For driving-licence rules, enforcement questions, or measured weight evidence, use the DVSA source, your plate, or a certified weighbridge.

Try it now

Set your region to United Kingdom, then open a trailer profile. The fields read in UK terms, with MTPLM, MiRO, and nose weight shown against the values you take from the caravan plate and documents.
loadmate helps you work from the numbers you enter. Keep your source documents handy, and use a weighbridge, truck scale, or local authority when you need official evidence.
