Hey guys. There was a thread on here about these storage boxes, but can anyone tell me what Buyer's website is? I want one of those Cage/Box storage systems that go on the front of the trailer up and out of the way. I need about a 4 footer and would like to just buy one, but I'm not sure if they make a 4 foot model so I need some info as to what their website is or if there is any other MFG. that makes these cages. Thanks guys!
