I am in the tree cutting business. From time to time I am either loaded up with a ton of wood or pulling one of our stump grinders. I need my truck to be able to handle the weight. Last week I ended up running over my mud flap and ripping it off my truck because my truck was riding so low. So would 2500 leaf springs bolt up to my 09 1500? Or would air bags be better? What else could I do?
