Adding Bumper Pull Hitch to RIG

oh gotcha yeah I would imagine there is quite a bit of difference in height between the two

my trailer coupler level is definitely higher then that....
I would like to weld in a hitch receiver in between the frame rails as a crossmember like you did. I think that is the most secure way to have the hitch installed ... My only concern is I dont want to have to use an extreme hitch drop
