Some people might poo-poo my choice, but I went with the Berkley cart linked below:
Berkley® Jumbo Fishing Cart | Berkley®
I needed something that would break down to travel conveniently in a compact SUV. It is pretty well thought out. It has eight rod holders, a bait station with a cup holder, knife holder, and scissors holder, and sand spike holders just above the wheels. I have also found a "hidden benefit" of this cart. It already has a place in the cargo liner to put a bucket, but I have discovered that the pull handle dimensions allow you to to slip a bucket down within it's rails. It will hang there perfectly, requiring a slight tug to pull it loose.
One thing that made me feel better is that I found out after I bought it that "Chris V" from the Pensacola forum uses one. If you keep up with him and his catches over there, you will find that he is one of the people in the GS/OB area that understands the area fishing on the same level with Pier#r. If fish are biting, it seems that Chris is on them.
Understand, if I were a local, or were willing to make my family travel in one of my pickups, I would have bought a traditional tube pier cart and added Wheeleez for the surf.
In my case, I like to travel (to the beach) in my wife's Honda Element AWD. It has rubber floorboards and waterproof upholstery. It's perfect for hopping in between wade fishing spots (or waterparks, with the family). It also has elevated rear seats (which all fold into a bed for naps) which allow rods to be stowed underneath. I can put more fishing gear on the inside of the Element than you can in a Suburban, while still maintaining passenger space. It's actually quite shocking. I just didn't want to have to attach any external racks for a cart if I could avoid it.
