When we purchased our RV we asked the service department at the RV Dealer what they suggested and the Service Mgr. gave us a list of general tools that would help us with basic maintenance. We bought the needed tools at Lowe's and kept them in an old tackle box. Over the last six years we have added three additional tools and it is that simple. There was nothing unusual on the list and we have used everything we bought over the last six years. Pliers (various), wrench, screwdrivers, a hammer, grease and grease gun and a few replacement nuts and bolts for things that may vibrate off when traveling. Since our first couple of trips we've learned what to check before we travel and it has helped.
