ARB Simpson III Rooftop Tent Installation
With the ARB Simpson III Rooftop Tent in the driveway I first inspected the packing looking for any external shipping damage and found one corner of the box crushed. After photos of the corner I finished unpacking the tent which I found to be double boxed with the outside box being heavy duty. Even with the external damage the packing protected the tent well and I found no problems.

With the tent unpacked I found the stainless steel mounting hardware in a small cloth bag and the rails inside the tent.

Wanting to mount the tent on my M416 military trailer I spent an afternoon constructing a rack. Following ARB’s instructions I cut the cross members down to allow them to be mounted across the rack. The original bolts were not long enough for my rack so a quick trip to the hardware store provided longer ones. Placing the tent on the rack took two people with one on each side. The rack was only about 4 feet off the ground so I can say that lifting the tent onto the roof off a lifted truck is going to be a chore.

The tent mounting system allows the tent to easily be centered on the rack. Some rack systems allow the tent to be mounted directly without the provided rails. With the tent set I tightened the rail mounts.

Installing the ladder took only a few minutes.

I opened the tent and marked on the ladder where I needed additional holes for the adjustment stop.

After drilling the additional stop holes I opened the tent , lifted the mattress, and finish tightening the tent mounting bolts.

The final part of the installation was to mount the tent cover on the tent platform. The design allows the cover to neatly slide into a groove on the hinge side of the platform. Even though the installation does not call for it ,I am going to use two small sheet metal screws to keep the cover in place.

With the cover installed I proceeded to stow the tent, ready to head out for a weekend excursion.

The installation instructions were clear and concise with quality hardware provided. Though I completed most of the installation by myself, a second person was needed to set the tent in place on the rack.

Hello Tomas-
First off, thanks for the review, it was very helpful. Second, I wanted to put together the same kind of set-up that you have and had a quick question on the install.
How do you raise the support bars for the base of the tent, when the tent is installed. From what I understand, the tent has some weight and was wondering how hard it would be to have the support bars be lowered for transport and raised for camping.
Any pointers on this.
Thanks in advance.
Rick
I pull the pins out and lift the bars while standing on the trailer then re-insert the pins. The Hi-Lift jack could also be used to lift the bars.
hey dude, how much cost you that tent, im from venezuela and i need one! thx
I have no clue what the cost would be in Venezuela. I recommend you look ARB (http://www.arb.com.au/) site and see if you can locate an international dealer.
Thanks for ur review, just bought one and went camping on the weekend. Love how it’s so easy to set up and how it catches a nice cool breeze. The only problem we have is getting it up onto the 4wd. It’s just so heavy. Any ideas on how to make this task a little easier on my back?
