Series III Simpson Roof Top Tent - Annex Included - by ARB

ARB is one of those brands that doesn't need introduction. Its world wide leadership and recognition are well deserved. Top of the line quality and classy, well thought design have maintained the Australians on the top, tendency-setting area of the 4x4/offroad/overlanding industry. 

This roof tent is truly special, it evolved from its predecessor the series II. It's re-design took more than 6 months in the making and a new factory for improved quality assurance. The update incorporates a new design and better materials to increase weight limits, strength, UV rigidity and water resistance as well as an Annex.

This tent is made to provide the most convenient and easy to use experience while car camping where ever you go. It opens and folds in minutes using its bungee cord system that keeps the walls tucked in to speed up the process so you can be back on the road as soon as possible.

The ARB Series III Simpson Roof Top Tent is made by extreme overlanders and thought for the same kind, its construction was guided by people who know by experience what, when and how we need a RTT to be, from its structure and canvas to its outer looks and materials.

It will give you that feel that all ARB products have; high quality and durability. This off the floor tent will fully protect you from the outdoor elements and wildlife. Just imagine your next journey with such a great tent, classy, durable and high quality. Its 2.5" thick, high density foam mattress will make you sleep like in home even in the most extreme of off road adventures.

Once your order is signed for at the delivery point, the package becomes your property and thus, our liability ends as far as shipping damage is concerned. Help protect yourself from loss or damage, or an uncomfortably painful claims process by:

1. Before Signing for your order, inspect the box or boxes for freight loss or damage. Red flags are punctures or any sign of forklift damage.

Please take photos of the box on the pallet exactly as it arrives. Please note, the driver will not help with damage inspection. IF you even suspect there could be damage to your item, please take pictures of the damage and REFUSE the delivery. That way the carrier will send it back to us and we'll process a new shipment.

4. Get a copy of the signed delivery receipt that shows the freight loss or damage notation, and send it to us:

Step-By-Step Guide On How To Mount A Roof Top Tent:

  1. All tents have a similar installation process, but they might vary a little, that is why we recommend you reading carefully THROUGH EACH PRODUCT MANUAL, as well as watching their videos (most are online, or you can ask us to send them to you).

  1. Tools needed: A Phillips head screwdriver, a box cutter, a second 13 mmm ratcheting wrench, a 10mm ratcheting wrench and a heck saw.

  1. Before mounting them onto a roof rack, flat rack or crossbar, the first step is removing your newly bought RTT from the box, as well as all the bits and pieces included (all RTTs WILL include all the necessary installation parts and a manual).

  1. Take the tent out of the box and place it on a clean surface with the straps faced DOWN. Set aside the mounting racks. Remove the protective plastic from the tent with the box cutter. Undo the straps from the sides of the tent and across the base.

  2. Open the tent, and take from inside of it all the contents. Most brands will include a tent cover, rainfly, ladder, mattress, and a pouch with the hardware, tools and parts.

  1. Most RTTs will include the following tools and hardware (see Image as an example): 2 bungees, 2 ladder brackets, 8 aluminum channel sliders with bolts and nuts, 4 end caps, four steel mounting plates, the needed wrenches, and four medium sized bolts with washers.

    tools included inside roof top tents
  1. Then, time for the action. Grab the mounting tracks of the RTT; place them on the tent base parallel to the hinges, aligning the holes in the tracks with the holes in the base.

  2. Grab the nuts, remove them from the four medium sized bolts and slide them into the mounting channels, as to align them to the holes in the base.

  3. Then take the bolts each with two washers, and slide them between the mattress and the tent base.

  4. Screw them into the pre drilled holes and the nuts you just put in the tracks.

  5. Once the tracks are on, you need turn/flip the tent over to install the ladder.

  6. Grab the Ladder Brackets and unscrew the bolts on each bracket, so that you can position over the pre-drilled holes at the edge of the tent base.

  7. Take the longer bolts each with the washer, and slide them between the mattress and the tent base, into the pre-drilled holes and up through the ladder bracket.

  1. Attach each one with a nut and leave them loose.

  1. Then grab the ladder and through the holes at the end of it, join it to the by passing the remaining length of the bolt through the holes in the ladder end. Then add another nut and tighten it on both sides.

  1. Then rotate the ladder a few times, before tightening the bolts of the brackets to the base.

  1. Then secure the ladder with the straps (most tents should have them), and then reattach the side straps of the tent to secure it. 

  1. Once all the parts have been installed, make sure you put the travel cover on top of the tent. It is a very easy process that barely needs explanation; just make sure you close the zippers carefully to prevent the tent fabric catching to the zipper.

  1. Time to place the tent on top of the vehicle. Since they weigh over 120 lbs, you will want the help of someone to do it. 

  1. Mounting the tent mounting tracks depends on whether you have side rails or cross bars, and if you want the tent to open towards the side of the car or towards the back. In this step-by-step guide we will use a side mounting as an example on top of cross bars.

  1. Place the mounting racks in the base of the tent, PERPENDICULAR to your roof rack bars.

  1. Then, fit two aluminum channel sliders and bolts into each end of the mounting track, so that there is a bolt on either side of the roof rack bar. Repeat this process at each of the 4 points where the racks and mounting racks cross.

  1. Once this is done, fit a steel mounting plate on the bolts and under the roof rack bar, and secure them with nuts and tighten them with a wrench.

  1. Insert the rubber end caps into the end of the mounting tracks to avoid water or other materials going in there. You might need to hammer them in, but don’t be too aggressive.

  1. It is INSTALLED!

How To Open The Roof Top Tent:

  1. Now, to open it, release the side straps, pull back the ladder until it locks out and use it as leverage to open the tent.


  1. Make sure all rungs of the ladder are locked into the edge.


  1. Before getting into the tent, make sure the hinges are properly engaged.


  1. Then unclasp the awnings and find the predrilled holes for the rainfly rods.


  1. Insert at a 45-degree angle and hook through the grommet.


  1. You are READY!

Very happy with the Annex


Ask a Question
  • Is this rated for all 4 season? Does it have a sunroof? Is the mattress anti-condensation?

    This is mostly a 3 season tent, but it can be used in all 4 seasons if you have the right bedding, or a good sleeping bag. The tent itself will hold under the snow.

    No sunroof or sky window. 

    And no, no anti condensation mat included unfortunately.

  • Is an extension for this ladder available?

    Yeah of course, it's included as a variant in the product itself. Please check the drop down menu which reads "ladder extension".

  • Hello, I can't really decide between ARB or TuffStuff roof top tent for 3 people. Both comes with Annex which is good as if my all kids will go with us it has extra space to sleep. Any suggestions? Plus may be something else with 3 people plus Annex. I open to listen your suggest beside those two tent. Thank you

    Hello! Well, both are very good options. Very similar in quality and both great brands. Between these two, I'd say that you should go with the design of tent you like the most. For example, I preffer the entrance canopy design of the Tuff Stuff.

    Now, I do have one recommendation, check out the Wanaka Roof Top Tent by Guana Equipment. (Link below). I suggest this one because it has an XL Annex that will work great for when you go camping with kids, also the quality of the tent is a step above, and it comes as a full setup with a bunch of accessories that neither of the mentioned by you have, so in the end, price-wise it is very good.

    Hope this helps. Please let us know if you have more questions.   

  • What type of rack do you recommend for a hardtop wrangler Jeep to mount tent. I have a Yakima that I carry a canoe with but sure roof won’t handle load of tent and 2 people

    Hi, we definitely recommend a full roof rack if you're going to be using a Roof Top Tent. Our recommended rack would be a Front Runner Outfitter Slimline II. There are quite a few, depending on what Wrangler you ahve, we should have it. Look here: 

  • Will you RTT fit on my 2015 Ford Explorer Sport? Also, I saw a Youtube video showing your RTT with the ladder and door on the back of the vehicle instead of the side. Is that feasible with my Explorer? I like your product. Thanks in advance for your response.

    Yes, this RTT will fit perfectly on your vehicle. You'd just have to find a good roof rack, and you're good to go. And yes, you can set the tent to open either to the side or to the back. Send us an email to if you wish more info, we'll be happy to help you out.

  • What color is the tent cover for when the tent is closed?

    The color of its travel cover is gray.

  • What is the length of a full extended ladder. ? I modified my set up and now it is 91" off the ground. Will I need an extension? Thank you - Chris


    Yes, you'll need an extension unfortunately. The ladder will work with setups up to 85-87".

  • What are the dimensions closed?

    The Closed dimensions are: 55" W x 47.2" L x 12" H

  • Does the Annex have a floor or is it open to the ground?


    Great question. Nope, the annex DOES NOT have a floor, it is open to the ground.
