I was wondering if anyone has ever used these trimmer racks by RACK'EM before - http://www.rackemmfg.com/open-trimmer-rack.html . I need to get some racks for my open trailer. I really like how the trimmers are held in. Seems like they wont bounce around too much. I have to attach these to wood sides on my trailer. Do you think the wood sides would be strong enough to support the trimmers + racks?
