To install, simply line up the carrier rack and fasten the U-bolts to a square 4 in. to 4.5 in. RV bumper along with the bike carrier racks and the L style tie-down bracket. All necessary hardware is included.
We bought this product to use on our 5th wheel.
I works well although the holes for the "U" bolts were misaligned and had
to be redrilled for the "U" bolts to fit properly for installation.
Once installed the bike rack did an adequate job of carrying our two bikes.
For the money I would say it was satisfactory.
Would I recommend it? Only if you wish to go inexpensive
Is it good quality? I would say more or less; but nothing to brag about!
