I just finished mounting my brand new Mombassa RTT, the "upgraded"poly/cotton ripstop". I don't have much to compare it too, as this is my first RTT, but so far it has been great. The mounting was no problem, all the pre-drilled holes lined up where they suppose to. The fabric seems pretty heavy duty compared to a ground tent. It is not heavy canvas nor is it lightweight nylon. Kind of a combination of the too. The material reminds my of summer weight BDU's from my Army days. I can see it being warm when buttoned up in the winter and it is ventilated well, for summer time. The mattress is 2.5", and is very comfy, although I still may use my double thermarest luxury mattress on top of it. Not sure about that yet. I LOVE the window supports, they are strong and beefy and allow lots of airflow. The rainfly attached to the tent all the time, (sewn at the top), but it gets held up and out of the way if you want it too be. The floor is aluminum ish? Not exactly sure what material it is, seems plenty strong. The screen material seems a bit thin, may have to replace that someday. I mounted it to a "Front Runner" Bakkie Rack", on the back of my Power Wagon and the base of the tent sits 12" above my bedrails, yet still out of the wind behind my cab--nice. I paid $899.00 plus some extra for shipping from TRDParts. I was planning on actually getting the new ARB 3, which I found for $1384.oo but I had to spend almost 500 bucks for the Bakkie Rack to get it mounted and still get use out of the bed of my truck plus keep the tent on it, so I pretty much felt it necessary to go with the Mombassa, as I needed it now, not later, and funds are limited of course. I am very happy with it and look forward to years of use.
