I have a covered wagon I built using the wheels and axels of a garden cart. (See attached pics) I want to motorize it to make my life easier. I use it at the Houston Livestock Show and Rodeo to provide food for my team of volunteers. I have to take it quite a good walking distance rain or shine. It is 2x4 foot with 10 in wheels. Run time is approximately 3 to 4 hours a day (going in the rodeo and leaving) with an idle period of 6 to 8 hrs between.
