Maybe this tool list could be helpful? (Kits no longer available) I designed, built and sold 1000's of these trail kits for years until covid killed the DeWalt supply chain. We found the combination of SAE/Metric and adjustable tools seemed to cover most roadside/driveway repairs/maintenance. (Throw in some torx for the newer trucks/jeeps/etc.....) I run one in every vehicle we have and seems to work for those common problems you run into.
BTW....Good job Dad!
