CCB made a good point! You can do what you want with your cart, even ad sides for storage up to the DOT guide lines for tow trainers. You will pick up a lot of things as you go. The good thing is what you spend is not a waste of money and if you make a mistake you can fix it at little or no cost, the main thing is to get going and make some money while the weather is great and all the fairs and events are going on.
