I live in the northeast where it goes from hot to cold during the year. To make life easier and not move gear 4x's a night, in and out of vehicles and at the venue as well. I've acquired a cargo van to store speakers, pa amps and outboard gear, lights, drums and hardware in to make life MUCH easier. Are there any concerns I should have other than allowing everything to acclimate to room temp during winter before powering on?
