I finally purchased a Kelty Noah 12 tarp for my winter adventures . I've set it up in winter mode a couple of times but seem to have a problem getting doors resemable tight. I can get tarp nice a tight, about 5' high about 5' wide at floor but doors seems to be too long and i need to pull that way back in towards center of setup length wise. This is creating a funnel effect for the wind at both ends...

Anyone have any tips to setting this tarp up in a winter mode with doors???
