I have 1 tube 100mm and can get in 3 poles and 5 spreader bars with a bit of fiddling - wing nuts stay on and its alternate the way they go in .. the 2 tent internal support poles now live in the tent . I think I'll be doing another tube to make it easier and to hold an umbrella , trekking poles , tripod and my new toy a stunt kite ...
Cheers
Steve
