Simple but versatile tool or tools to keep in the truck recommendations

Hello Everyone.

I was wondering if I could get some recommendations on a couple of tools to keep in my truck.
Looking for something that's simple but versatile. And that can be worked with the minimum of force but can handle tough on un/tight/ening screws something that can handle different sizes of screws and nuts. That can be used for what ever small adjustments around the truck or things I carry on it. Like for example bicycles, skates, for removing or putting up bike racks, roof racks, bed racks etc, etc.
Something that can handle from small screws to some that can have up to an inch diameter heads.


Thanks in advance.

 

Craftsman has tool sets with various sae and metric sizes, could also grab a few of their screwdrivers as well. Home Depot sells some decent pliers individually as well. You could get a small tool bag for the screwdrivers and pliers etc. Keep the craftsman set in its box behind the rear seat.
