i'd go the trailer personally, you can heap shit in to them, dent them, weld bars/racks/frames on them as you please and when you're sick of it... roll it behind the shed - whereas if you've got a ute/pano and you're putting stuff in and out and generally using it for work, it'll get dented up and scratched and dirty and smelly(no matter how careful you are)
i've got an old 6x8 box trailer, with a removeable frame/canvas cover/racks on it, compartments on the outside for jerry cans etc.
i've used it doing part time landscaping, moving stuff around the farm, carting bikes/hay bales/gravel/tools/furniture/plants/beer and it's sweet... all i need are a set of Ford mags and a new paintjob for it!
just my opinion...
