i bought a 5x5 gorilla tent, i had to send it back cuz it was impossible to get the tent zipped up, i had 2 other people helping me, trying to pull the top half down to connect to the bottom half. it seemed like the top was 2 inches short to reach the zipper on the bottom half. this prolly sounds confusing, it's hard to explain lol. anybody else have trouble getting this tent set up?
