Have yet to use my modded TT SCARP 2 in a heavy snow with the two X-ing poles beneath the fly. Additionally I have a custom made, stronger main pole. This winter I’ll do my best to be a snow storm chaser and test it.
It’s a good tent in heavy winds with those two X-ing poled and side and end guyed plus 4 fly hem stakes. As I call it, “Braced, guyed and pegged down”. By burying the main pole ends in the snow a few inches the fly will be even lower and dead men will be used for fly stake loops.
My only concern is the SCARP 2’s vertical and rectangular ends. They are not aerodynamic in the least but I have them modded so they too are staked down at the center. I can open the end zippers a bit for venting and still control their opening size against the wind making the opening larger. So far, in gusts up to 60 mph., they have been very “unflappable”. (Sorry, I couldn’t resist.)
