Rental trailer in LA area?

I'm thinking about doing my first track day mid April up at Streets of Willow (with Speed Ventures). Don't really want to drive the Elise up there so want to find a good trailer to rent.

Any suggestions for something more appropriate in LA (preferably Southbay area) than just getting a U-haul? My tow vehicle is an '08 4-door Jeep Wrangler with 1-1/2" hitch.

Appreciate any thoughts or input. I've read the track day posts (great info), but if there is any advise specific to that track would appreciate that too.
