I'm waiting to talk to the owner.. I've called him and he's stillout of town.
trailer is parked roadside.
looks like it was purpose built.. IE.. a MH frame, decked, and from the look of the new wood, it was likely used 1x or 2x to haul something long from the scratch marks and loading marks... is listed cheap.. but we know how that goes. trailer wiring is the 4 wire flat bulk stuff with a round 2 wire doubl einsulated piar by it's side. just ziptied along the fram, ran down one side tot he lamps, then across the rear to the other lamps, and across the axles .
obviously a fast wire job.. the 2 wire is for the brakes.. with the 4 flat, for the regualr lamps and such. generic 'round' (cheap) universal tail lamps and license plate lamp under one. etc.
my guess is a scrapper built it to haul a ? cargo container or roll off. or something.. tossed 25$ of lamps and wire on it, all but connectored and zip tied.. hot dfst and dirty, used it now is unloading cheap.
least that's my 'feel' from looking at it. based on what I've seen from looking at old stuff for sale by the roadside for years..
