Payload Reality Checker

A calmer way to see how quickly payload disappears once real caravanning items start climbing aboard.

Caravan figures

Caravan MIRO (kg) Mass in running order — the caravan's starting point before your extras and luggage. Caravan MTPLM (kg) Maximum technically permissible laden mass — the upper legal limit when loaded.

Typical caravan load

Leisure battery (kg) Gas bottle(s) (kg) Water / aquaroll / onboard water (kg) Awning / porch awning (kg) Mover fitted (kg) Food, clothes and bedding (kg) Extra bits that always appear somehow (kg) Chairs, levelling blocks, hook-up lead, tools, spare odds and ends, and all the other “light” items that somehow aren’t.

What this tool does

Shows your official payload allowance from MIRO and MTPLM
Adds up the usual real-world items people forget to count properly
Shows remaining payload — or how far over you have drifted
Explains what the result means without the usual drama

Why payload causes so much faff

Payload sounds generous until batteries, movers, awnings, food, clothes, water and the mysterious pile of “small essentials” all start taking their share. This checker is there to show the maths before the caravan quietly becomes heavier than expected.

Overall verdict

Plenty of breathing space

This looks comfortably within payload.

You still need sensible loading, but there is useful headroom here rather than immediate cause for eyebrow-raising.

Official payload allowance

150kg

MTPLM minus MIRO.

Estimated loaded items

165kg

Your current entered load total.

Remaining payload

-15kg

If this is negative, you are over the allowance entered above.

Estimated loaded caravan weight

1465kg

MIRO plus your entered load items.

Load breakdown

Real-world context

Payload is one of those areas where caravanners often assume the margin is bigger than it really is. A few perfectly normal items can eat it very quickly.

Payload reality check

Allowance 150kg • Estimated load 165kg • Over by 15kg

It adds up faster than most people expect.

Common payload traps

Counting the awning but forgetting the battery or mover
Assuming “a few bits” weigh very little when together they do not
Using MIRO as if it represents a ready-to-tour caravan
Carrying water and gas without really allowing for them

Important note

This is a guidance tool, not a substitute for using your actual plated figures and weighed items. If the numbers matter, weigh what you carry rather than trusting optimism.
