Since i have to cross thru national parks at 2am to save time during the day since most of my meetings are at 11am... and many night travel crossing very hostile zones and hours from civlization
My standar equipment in my Fabia consist of:
Spare tire, Tire inflator/sealant, electric air pump, tire repair kit, metric tools from 8mm to 18mm (ratches and wrenches), screw drivers, allen keys, torx bits for the screw drivers, a spare belt, gallon of destilled water, swimming fins, swimming shorts, soap, towel, swimming gogles, a tent, two fire extinguisher, one first aid kit, ropes, tow tools, tie racks, no.12 wire for any electrical issue, a multimeter, swiss knife, a Machete (dont ask why, i just like how it looks) two flashlights, 120w inverter, solar trickle charger, insect killer, torch gun, with 3 cartridges, an umbrella? a jump star cable, a jump starter, a life saver (my partner doesnt know how to swim) and a shirt, pants, underwear and shoes.. all very well acomodated and distributed between the front sas, the golve box and the trunk, visible only the gallon of destilled water, the life saver the jump starter and the bag with swimming stuff and the tent, so the trunk is clean and empty lol
And some times i take the power generator with me
