ARB Simpson III Roof Top Tent install – set up #travel #overlanding #camping

The ARB Simpson III rooftop tent delivers the ultimate in ease and convenience when traveling. Unfolding in minutes, a rooftop tent provides sleeping quarters off the ground, protected from the elements and wildlife. All bedding can remain inside the tent during the journey, freeing up vital storage space in the vehicle and allowing the tent to be quickly and easily packed away. Also aiding the fast pack down and setup, a unique bungee cord system keeps walls tucked in to assist in speeding up the pack down to get you back on the road faster.

Preparation of the tent for installation

I have provided a link to the “owners manual” but while ARB make great products, their assembly instructions are not the best. A post will follow to demonstrate how I installed the RTT on my rig but the stages and images below explain the preparation that needs to be done first to assemble the rails to the base of the tent that will be seated on your roof rack.

1. Unpacking

Note that I have removed the mattress that comes with the RTT for this installation. It usually sits on the base and in the image below would be sandwiched in between the folded floor.

2. Extended

In order to get access to the interior to secure the bolts for the rails, you need to open the RTT on its side as shown.

3. Attaching the rails

The rail attachment is straightforward. Simply thread a bolt through the base and align it with the rail on the outside. As the nut needs to thread in to the rail extrusion on the outside, you have to do this step first before trying to fasten it to the RTT base. A screwdriver can be used to hold the nut in the rail as you locate the thread.

It sounds more complicated that it actually is but giving yourself lots of access inside the RTT will save time on this stage. Hence why I removed the mattress.

4. Rails in place

The images below shows one rail in place and you can see visually on the right image where the nut needs to be located in the aluminium extrusion. Note it is recommended to have the rails mounted so that the fixing is on the inside of the rail as shown.

Completion
