Adding a Rear Receiver Hitch to my Micro Minnie. I removed the original sewer bumper and cut off the original frame mounts, to allow mounting of the new bracket.
I Designed the new 3/16" Thick bracket that extends further rearward to make room for the 2 1/2" x 2 1/2" x 3/16" or 3 x 2 x 3/16 wall HSS crossmember in behind. I chose to go with the 2 1/2 for more vertical support. The original Sewer Tube will weld to the new bracket and the Spare Tire Mount will weld to the top of the 2 1/2" receiver tube.
The Bike Carrier Receiver Tube will sit on top of the crossmember and above the sewer tube for more ground clearance.
The new bracket will mount to the frame via the original bumper/sewer tube mounting holes and supported by the stabilizer jack bolts along with one additional bolt towards the front of the trailer on the bottom of the frame (to be drilled).
The 4" sewer tube will weld in front of the 2 1/2" x 2 1/2" crossmember to the two C Channel brackets and to the underside of the receiver tube.
