Trailer and Vehicle Loading explained

What does GVW mean?

GVW – or GVWR – means Gross Vehicle Weight, or Gross Vehicle Weight Rating. It’s specified by the manufacturer and refers to the MAXIMUM weight a trailer or vehicle can be when fully loaded. In other words, it’s the unladen weight of the trailer or vehicle (kerb weight) and the maximum payload combined. Using the stats for the Vlemmix TH600 tiny house trailer, the equation would look like this:

2,930kg (payload capacity) + 570kg (kerb weight) = 3,500kg (GVW)

What does GCW mean?

The Gross Combination Weight (GCW) – also known as the Gross Combined Weight Rating or Gross Train Weight – is the weight of a trailer and towing vehicle combined as specified by the vehicle manufacturer, including the weight of the maximum loads on each. To calculate the GCW for your tiny house trailer you can simply add the maximum weight of the trailer to the Gross Vehicle Weight (GVW), as demonstrated in the equation below:

GVW + maximum trailer weight = GCW

What does trailer payload mean?

Payload is a term that crops up a lot when dealing with transporting goods, whether that be a boat, luggage or a tiny house. It refers to the MAXIMUM amount of weight which can be carried on a vehicle or towed on a trailer, and can be easily calculated if you have access to the Gross Vehicle Weight (GVW) and the unladen weight of the trailer or vehicle (known as the kerb weight or ‘curb’ weight). Simply subtract the kerb weight from the Gross Vehicle Weight, or reverse the equation to find out the GVW.
