It's been a lot of years since I have done a tent set up, but it would seem to me that as long as the Geni is not supporting the tent roof that it as a piece of equipment, much a seperate piece of equipment givent the roof is self supporting has little to do with the tent roof if if blows or not away. Big long stakes drilled into pavement and large ratchet straps, two per post the main detail.
In any case given a misunderstanding on my part that the lighting rig is seperate from the tent roof in general, the GENI lift system of hanging the truss should with legs be sufficient to prevent problems in the wind for a standard rig with or without tent over it. Granted for a large storm I would tend to lower it, but I just can't see some Geni tower ending up in the parking lot.
If in question, in the past, I have found that if arranged for, the tent guys are very reasonable in drilling and staking a few holes than tying your tower also down in it's own system of support.
While I have not done such a thing, I expect such a seperate derrived system of roof and truss, much less support for each individually would be sufficient for a storm, much less allow the truss to come down as desired fast without worrying about wet tech people even while doing so. Asleep on the bus on route while the tent guys worry about the tent roof in the parking lot or what ever the next day.
5 years in doing special events for Chicago - granted as a Carpenter, never saw a tent just blow away. Could happen but I expect the lighting when seperate has seperate worries than the tent and you no longer have to worry about the ballas6t of a tower in counteracting the wind.
Just a thought.
