Start with a competent vehicle
When looting and mass chaos ensues, you could have your pick of fancy-shmancy sports cars, but what good will a Ferrari do when the roads are clogged with hordes of skin eaters? You need something that can go off road, and do it with aplomb.
That means four-wheel drive and significant ground clearance (just imagine the piles and piles of carcasses, guys) like a Jeep, a real SUV (not a car-based crossover), or even a full-sized van, provided it’s a 4x4. Avoid trucks, though. If you thought hop-ons were bad on the Bluth Company stair truck, try dealing with decaying mutants in your truck bed.
