This is such a unique subject based on location and needs. Divers out of Ga have a great enclosed trailer setup where you can stand and store gear. DiveMedic trailer is awesome, but i watched him hit his head a couple of times when moving gear (sorry bud, had to point it out) and the trailer greg posted looks like it would be great for access and easy to move but good luck changing, drying or securing all of your gear. That being said, i use a four door pickup with a toolbox for light gear. It works but it is not the best solution either...
