I have had my JB Space RTT over 3 years and estimate I have spent over 140 nights in it. It was an early to North American model and so I expected a few glitches to show up, because of the limited distribution and field use in North America at that time. European camping is not as extreme as in North America, but still it looked like it would stand up. I saw them first in Moab in 2014. The only issues have been, early on the ladder hooks broke and last year the solar fan needed replacing, but Adventure Ready in Seattle promptly addressed those issues. A few zipper pulls have broken, but I have replaced those with ones with rubber insert pulls, which are nicer to the touch and not as cold to the hand as metal. Some of the black paint on the hooks has come off (should be stainless steel) but that is easy to touch up. The solar fan is a excellent at venting respiratory water vapour, keeping the exterior of my sleeping bag dry in the morning.
The tent is hard to close, but I have accepted that disadvantage because of the incredible strength of the struts. The tent has has survived brutal wind gusts and pounding rain through many tough nights - without damage. I extended the rear pull down strap, with some nylon rope, so I can use my left foot to pull down the rear of the tent to allow east latching. I wax the exterior and wash the fabric sides each year and treat it like a fibreglass boat. It has been taken through dense bush and forests and the branch and sap marks can be polished out. Over the winter I have fitted a 100 watt solar panel and put some marine Hypervent fabric under the mattress - so we we will see how well that works out. We are planning a 4 week trip to Utah and Arizona this May. Overall I am very happy with the JB RTT, but like any equipment it needs to be taken care of.
