If I wanted a cabinet, I'd buy a cabinet. If I wanted a trailer, I'd buy a trailer. Not going to take the time to unload the cabinet, convert it to a trailer, haul my stuff, clean the trailer, convert it back to a cabinet, and then reload the cabinet every time I needed to haul something.
JB is right. You can get a lot of days local rental from Uhaul for $1300. Even renting a truck from Uhaul, Lowe's or Home Depot is going to be cheaper in the long run if you're only using it a couple of times a year at most when you figure in original purchase price, tags, insurance, maintenance, and excise tax in some states.
I think a 12x6x5 ft tall tandem axle Uhaul trailer was about $50 including tax for the day with unlimited local mileage the last time I rented one. A 14' truck wasn't much more.
