Danny,
It really depends on where you're scouting.....Here in San Diego Co., most places have good road access.....So any car, suv, or truck will do....Once you pick an area, your vehicle should have these essentials.....Water, snacks, TP/baby wipes, tarp, good jack, spare, good flash lights, tools, tow rope, duct tape, baling wire, shovel, charger for phone, bug spray, and a change of cloths.
After leaving the vehicle, good boots, wear a belt, walking stick, water, snacks, LED flash light/extra batteries, good backpack, binos/tripod, camera/cell phone, and that TP again.....lol
Sure I left something out, but I think you get the idea.
