i have that hitch on my jeep(the one you posted up) holds up real well! and im not pulling anything near that weight..i think you arent straining that ford at all..you got the banks kit..which 1?the big hoss bundle allows you to have the most power at the safest level..i would check that out..if you upgraded the tranny..(i would put the banks torque converter in tho..) you have the gears..and if it isnt struggling at all..you are good to go..

PS i posted up 2 pics of the jeep muddy..lol..at your request..
