Bought a Curt bumper receiver (
Curt RV Bumper Hitch) that I installed on the TT bumper - that's where the hitch goes when I park the TT (I use a Master Lock Hitch pin (
Master Lock hitch pin), so it cannot be stolen).
As for the bars, I installed 4 J-hooks to the front pass-through storage ceiling (bolt heads are basically inside the left wardrobe unit and under the bed mattress); each pair of J-hook supports a bar. No need to clean the grease, and being away from the storage floor, no mess.
