To do what you ask? In 45 years of on road driving, a 1/4" ratchet and sockets, and an assortment of hand tools has been sufficient to make roadside/parking lot repairs with the exception of flat tires, maybe I've been incredibly lucky, and I hope that this RAM continues the winning streak. I do maintenance and repairs in my garage with a large selection of tools. If I were to carry all the tools and parts to make repairs that might be needed, then there wouldn't be much payload left. I find this tool kit ideal for tightening loose connections and replacing batteries and other small tasks. More importantly, it works well to help out family and friends with repairs of home appliances and with assembly/disassembly of furniture when moving. I do intend to add the necessary tools to replace fuel filters (and the filters), as I could see doing this on the side of a road. Also to be added is a scotch brite pad and wire brush for cleaning electrical connections and a roll of electrical tape. In the other compartment is a Noco jump box that should be large enough for our diesel trucks and to help out the random stranger. I would welcome ideas of other items that would fit in the small floor compartments. Thanks in advance for your constructive comments.
