Getting to know your GTM
Understanding key terminologies is essential to ensure a safe and enjoyable journey when it comes to towing caravans. GTM, or Gross Trailer Mass, is one term that every caravan owner should know. This blog will explore what GTM means, its significance, and how it affects your towing experience.
What is GTM?
Gross Trailer Mass (GTM) refers to the maximum weight a fully loaded caravan can weigh when its hitched up to your tow vehicle. It includes the weight of luggage, water tanks, appliances and anything else you have packed for a get away.
Understanding GTM Limitations
Each caravan has a specific GTM (Gross Trailer Mass) limit set by the manufacturer, indicating the maximum weight it can safely handle. Exceeding this limit can compromise the structural integrity of the caravan, negatively impact braking performance, suspension components, tyres, and handling of the caravan.
Calculating GTM
To calculate the GTM (Gross Trailer Mass) of your caravan, you’ll need to measure the weight on all wheels that way you are able to get the axle loads. This gives you the total GTM. It’s best to weigh your caravan when it’s fully loaded and ready for travel. You can do this at a public weighbridge or by reaching out to us at DwnUnder Weighing.
Remember to subtract your tow ball weight because that gets transferred to the tow vehicle’s GVM (Gross Vehicle Mass). This ensures you have an accurate measurement of your caravan’s GTM.
Implications of Exceeding GTM
Exceeding the GTM of your caravan can lead to several issues, including:
- Safety hazards:Overloading your caravan increases the risk of instability, reduced braking efficiency, and impaired handling, particularly during emergency maneuvers.
- Legal implications:Exceeding the GTM limit violates road safety regulations, potentially resulting in fines, penalties or loss of insurance.
- Increased wear and tear:Caravans operating beyond their GTM (Gross Trailer Mass) limit are subject to higher stress levels on components such as axles, suspension systems, and tires. This can lead to premature wear, increased maintenance costs, and potential breakdowns.
