Mine is an '88 Cherokee 4x4, with a 9500 lb. winch, and roof rack, 3" lift and 32-10.50's. Plenty of room for gear, my lady, and her service dog (standard Poodle). Gets me wherever I want to go, but have been in the 4x4 game for well over 45 years.
If this would be your rig you are looking at getting, plan on adding a Hi-Lift jack, and carry extra water (both you and the rig), some rations that will hold up for medium to long term non-use, some extra clothes and a jacket or coat. Depending on your mechanical ability also some parts like radiator hoses and a length of heater hose, fan belt and sme tools, and whatever else might be a weak point in the specific vehicle that you would be able to swap out in the field.
