I just received a Tarptent Rainbow, and tried to set it up free-standing with hiking poles. I could not get it taut, and there is quite a bit of the arch pole pocket that is still gathered after the tent was up. I could be setting it up incorrectly, but I suspect that the arch pole that came with the tent is too short. It is approximately 120".
I have sent an email to Henry, but I'm wondering if anyone with a Rainbow could tell me the correct length of the arch pole. Thanks.
