Amigo,
I bought an old travel trailer, stripped it down to the axels, installed a plywood floor & wind shield. Placed some rollers on the deck for easy loading & unloading. It is 27' long and hauls 2 Cat-a-Rafts end to end and a motorcycle. Putting a raft together to fish & then breaking it down is the pits. You don't need brakes on the trailer, and if you set it up right, you can also haul your motor cycle. Mostly you have to be careful of how you lash down your equiptment on the raft when you travel!! Its amazing how the wind & road vibration will loosen various objects.
