Check out Cabelas master built mag hitch hall. As an example.
I have a 03 Explorer with a 1 1/4" reciever.To Hitch Hall type rack. (A freebie)
Added six 1 1/2 x 24" gray PVC electrical conduit with white end caps, drain hole in each.
Secured with self tapping metal screws. Drilled thru two 1/2" holes in each conduit to accommodate a long drill bit. Three on each side of rack,facing the rear. I carry a 90 or 120 qt. cooler in the middle, secured with 1 1/2" unistrut bolted to the steel mesh to keep cooler from moving. one on each side and one long one the back side.
All held down with "Good" rubber bungee cords. Movable to fit different configurations.
All material from a lowes type supply house.
A Cheap and efficient way to gain more space.
I can still open the lift gate and or the window.
Right now I have a 90 Qt. Cooler in the middle,a bucket on one side and a 24 qt. Rubbermaid cooler on the other.
Have been using this setup for four yrs. not a problem, easy on and off.
I always get questions and compliments.
I'm Sure I'm this type of fit out has been used many times. This what I came up with.
