I've had my tent for a few months now and have spent a few nights in it and wanted to share my experience. I also have the problem with bugs and dust getting inside the tent when it's closed. Furthermore, I'm having a serious problem with insects getting inside when the tent is up. Since the doors don't actually seal completely I'm not sure what to do? I tried tucking the inner flap under the mattress to create a tighter barrier, but it didn't work. I was camping close to a river and my tent would fill with moths. I have no idea how to keep insects out. Also, no matter how careful I am I seem to always pinch the fabric. I've stained the fabric on the front where it comes in contact with the black foam as well.
On the plus side, my gas mileage is better than with a traditional RTT and set up is much quicker. However, I'm not sure it was worth the money. I was so excited for this tent and it's been one disappointment after another. Oh well, you live you learn.
