Hooked up my box trailer 8'x11' to see if my 4" drop tongue was going to get me level and it did and then drove it around to test out the Mopar trailer brake controller I installed and to see how it was going to follow the Gladiator. All went as expected. Perfect !
Fill the gaps with RTV ..But if you do what you are thinking and it gets sealed that way you are all set ! And Yes it is a pain to get the wires in on the right side but once you get a wire though " I used clothes line " and use a bit of grease slides right in !
I installed a Rugged Ridge Spartacus bumper with a winch plate and the Overrider bar ...and a X-Bull winch . Oh and it does retain the factory fog lights and it clears the Mojave skid plate with no modifications !
