I have been going surf fishing for a few days at a time about once a year. This year I decided that I didn't want to drag all my gear down to the water every day. Looked at the cost of surf carts and couldn't justify buying one. Saw one similar to this on another site and decided to give it a try. The wheels were under $20 for the set at Amazon the cooler was $15 at Wally World, the rest of the materials were from Home Depot. It's 1 1/4" PVC. The tongue is 1" PVC and slides into the 1 1/4" and pinned to make it removable for storage.
