I can barely stuff 30 feet of 1 1/2" hose in a Systainer 5. I do also have 3 tubes & floor nozzle in the bottom.
It would take a huge hose garage to hold that much hose.
The hose garage holds one 27mm 3.5m rather well but I would like to add a 27mm 5m hose to it which is a little less than 30' and not have to disconnect hoses but just wrap them up at the end of the day.
I suppose a double garage that would house 2, 27mm 3.5 hoses would be good enough for my purposes.
Why not just use a systainer? Personally, I'm not very enamoured with the hose garage I bought for my 27mm hose, so if I wanted to store a bigger or longer hose, I'd prefer to use a systainer anyway.
I suppose that is a good alternative but ideally I would prefer not to disconnect the hose. Maybe that is me wanting to much. Of course I am not always needing to use that much hose but I prefer to have enough hose so the CT is not underfoot when working higher off the ground.
I cut the bottom out of a sys 1 for my mini, I have the 27mm hose with the plugit cord in a cable wrap, it was impossible to get it in there without kinking the hose, going to do the same with the 22.
That is an interesting idea but I still think a double sized garage would be ideal. A cable wrap is something I should use. Right now I just keep a cord on top of the hose and systainers on top when packing it up.
