And you’re right about a scale model as a possibility. One of my grandkids no doubt has a truck and trailer toy that I might be able to use. I think this calculator on the Truck Science site is the ticket—if I indeed can use it once for free. Or even once for cheap. Otherwise I know the best thing is to try turning in a parking lot, but I don’t think I can do it before my friends get here with their equipment and materials. They do road work and are squeezing me into their schedule for just materials cost. I’m very appreciative and don’t want to hang them up. It’s a real opportunity.
