Original Twist Camping Trailer

Camping with a tent makes sense – a small package opens up to become a big thing. On that logic a caravan is a bit lacking; a lot of empty space is being transported. You start with a big thing and end on site with a big thing; a bit like putting up your tent before you leave home. What we are looking for is something that can be towed easily, full of all our kit, and then be opened up on site with minimal effort. A full off-grid energy system built in would be the cherry on top and a satellite dish that gets the footie running straight away wouldn’t hurt either. And that brings us to the Original Twist Camping trailer.

Ever had one of those tool boxes where the top parts push away to reveal the box underneath? Well this trailer is just a big one with wheels on. The door frames at each end support the roof and lift it just like a four poster car lift. You arrive on site, the roof lifts up, the sides pop out and the roof closes down on them. The links that control the movement of the sides are steadied with torsion bars and chain and sprocket ties so powering it all is quite simple. The drawing shows one half closed and the other open; in practice both sides deploy together. The roof lift easily copes with the weight of the solar panels, dish, awning etc.

The side pods can contain beds with lights and TV built in and/or a kitchen unit. The choice is yours.

A shower room can be fitted over the draw bar as a separate cubicle that is entered privately from the main living quarters.

This design could be scaled up or down. Here it starts as the size of an SUV, for easy storage and towing, but still sleeps up to 5 when you get there.

Heating is by a truck cab mini heat pump or gas.

The generous PV array raises an interesting question. If your electric tow car also had panels on the roof there could be significant range extension when all the panels are combined. In the new electric era tow cars will need all the help they can get.

So there’s the idea. Does it exist? No, not yet, but let me know if you would like to build it.
