I just picked up a new trailer for my ZR2. Its a PJ 5" Channel Buggy Trailer, which has drive-over fenders and a full width deck. In all the research I did, I found nothing but good feedback about them. They come standard with great stuff like enclosed wiring, sandblasted, acid wasted, and powdercoated frame.
5' slide-in ramps
5200# axles, brakes on both
