If you have an annex room then you block the whole back of your truck and render your tailgate useless and make it difficult to get anything out of the back of the truck. If you have a 270 awning then you don't need an awning in the back. You can keep the weight closer to the center line of the vehicle by mounting it closer to the cab.
But otherwise I would have considered mounting to open towards the back. But I had all those issues to avoid.
Did you have to do anything unique? Seems like the lift window might need to be held so as not to raise too far or does it sit comfortably under the RTT? I'm just curious how it all works because it does seem to make sense to configure like a two story outfit that would be nice in the rain.
My RTT sits on basic Yakima load bars (round) with aluminum rectangle tubing on top of them (running front to back) in order to mount the tent lengthwise; not low profile by any stretch (I need about 7'6" of clearance in parking garages/drive-thru's with stock suspension and 33's). With all of the above (pun intended), the upper rear hatch does sit comfortably under the RTT when fully erect. The ladder clears the edge of the hatch by about 1/4".Did you have to do anything unique?

I'm not sure if all annex rooms are built the same but the ARB annex has a removable 4th wall (vehicle side wall); I simply don't use it. The other two walls hug the contours of the Land Cruiser's rear-end fairly well. Understandably, it's not 100% bug-proof seal (and here in humid Florida, we have plenty of bugs) but it does appear to minimize them. Lastly, I never bought the annex with the intention of it being a dedicated bug-free enclosure (that's what the tent is for); whether we like it or not, bugs are part of being out in nature . Also, DEET helpsHow do you seal the vehicule side of the room around the back? My ARB awning room as 4 walls and no way I could
Seal it so no bugs would come in. And also, a little more info about what I have mentionned up-here, is that our rack os located in the center of my vehicule, so the lift gate would interfear with the latter.
So yep, again, to each their own.
