Something to keep in mind: all those racks mount to the existing Cherokee roof rails, which limits the cargo capacity to 150 pounds (Assuming the rack itself is rated that much).
Factor in the weight of the rack itself (20 to 30 pounds plus) and the spare tire (50ish?) and you've made a huge dent!
Then figure in the fluids you want to carry. 6 or so pounds per gallon of gasoline, 8ish for water. That's another 30 + 40 (using 5 gallon Jerry Cans each).
You've just maxed out the rack
No spare parts, lights, tools or whatever...
A typical "Safari" rack, mounted to the gutters, can have up to a 300 pound load.
Here's the one I want to get:
But at FOURTEEN HUNDRED DOLLARS, it's very LOW on my list :/
