Not sure how much a cricket weights. Rick Huff designed them and sells them here in Augusta. He can tell you. The problem isn't just the weight of the cart and car. When you start adding; generator, gas, jacks, spare parts, cabinets, tables, race suit, microwave, golf carts / 4wheeler ( which are lighter than golf carts),tool boxes, air compressor, grills, coolers, stuff, etc. it gets beyond what a 1/2 ton truck can safely HANDLE. It's not about pulling it, it's about handling the load and stopping the load.
I have friends that pull 24'ers with 1/2 ton trucks, but they can't add anything to the trailer other than BARE necessities.
