Expanding Expandables - connecting trailers in length

You know what’s better than one trailer? Two trailers! Or three, or four, whatever floats your boat. At Expandable, we get that. This is why our products don’t just expand longitudinal but are also suitable for being connected with several at once. In this article, we can show you how to connect two (or more) trailers in length, and what you need in order to make it happen.

Why connect Expandables?

Let’s start by answering the first question you will probably have – why you would want to connect multiple Expandables when you can set them up side by side just the same? Sure, you have more space, but you also have more space when you put two trailers next to each other without a connection. So what gives?

Connecting Expandables creates a space you wouldn’t have otherwise. It’s like that famous calculation: 1 + 1 = 3. It allows you to do things that two separate units cannot achieve. Furthermore, two connected trailers feel more spacious together while also still allowing for smaller spaces within those.

Two connected units offer your floor plan more freedom and help you create the perfect setup with ease. Today we take a look at how to connect Expandables in length. Let’s take a look at both.

Connecting in length

You can connect two trailers with their end sides. By inserting a floorboard and roof panel, you create one continuous space that still feels like the conjunction of two separate rooms. And you can do so in just four steps!

  1. Put them next to each other (between 90 and 140 centimeters), end sides towards each other, and lower them
  2. Expand their sides and floors
  3. Put in the floorboard to connect both trailers
  4. Open both sets of doors and put the adjustable roof panel on top of them, securing it in place with nuts

Not sure how that works? The video below shows it in detail.



The result is a space that feels connected, but can also offer some privacy if needed. The biggest difference with two separate trailers is that they remain connected. This means fewer doors opening and therefore less warm or cool air escaping, or getting wet when it rains.

Differences and additional requirements

Connecting trailers in length requires no additional modifications to your trailers. All you need is one floorboard and one roof panel per connection!

In conclusion

Longitudinal expansion is only one piece of the puzzle that Expandable offers. Your options multiply exponentially when you take into account the fact that you can connect trailers! Just think of the possibilities…

We hope we have given you some food for thought; if nothing else, you now know you need not limit your thinking to just one trailer.
