Have always kept a small medic kit in the Jeep, containing typical first aid supplies plus burn dressings, cravats, medications, surgical glue, trauma dressing, hot & cold packs, shears, occlusive dressing, power bars, etc.
Also have a mechanics bag with various tools, jumper cables, high flow air compressor(battery mount), tow straps, tie downs, flares, tire repair, etc.
Folding shovel, tarp sided blanket, poncho, fire extinguisher, crank & chemical lights, etc.
Picked everything individually to form my own kits which allowed me to be as compact as possible without sacrificing necessary items. The only items noticeable are the small compressor bag (10x12x4)containing the tool roll and the typical Jeep roll bar mounted fire extinguisher. Everything else is tucked away and always on board if needed.
