While I don't have a backup camera system, we do have a tire monitoring system. It was great for our 2007 trip to Alaska. It is really great for detecting low pressure as well as high pressure. We did not take any extra tires beyond the spares on the Monty and the TV. We did get a 12 ton hydralic jack to change tires and a 4-way tire tool. I used these in Nevada after our return. I also put in a 12 VDC air pump to supplement my 120 Volt AC system in case we broke down on the road. By the way, cell phone service is spotty at best--so you break down service will not be able to help you because you will not be able to call them. So be prepared. The only other extra item we installed was a 5 cubic foot freezer in place of a recliner for our fish--we brought back about 100 pounds of fillets! The freezer is also nice for other foods when there is room. I also recommend Mike and Terri Church's book on Alaska Campgrounds--it is avialable on Amazon. And get the current years Milestone for excellent travel info. Have a great trip!
