In my case, I took the spare tire and mount off the back bumper, I have two cruiser bikes, light weight, I figure they are no heavier than the spare and it has been bouncing down the road for five years, Check welds for failure and things are still looking good! My swagman bike rack has a wedge built into it to reduce bounce and wiggle.
x2 The Swagman hitch receiver with the built in wedge makes the bike rack solid as a rock and because the Swagman bike rack stores the bikes resting the weight of each bike on the wheels of the bike rather than the frame of the bike the combination is unbeatable if one is concerned about any movement.

In this pic I didn`t install it yet, but the setbolt goes in from the top of the hitch, the starp isn`t on it yet either.
I also used a setbolt in the reciever against the bike rack to take out the vertical movement. to top that I used a ratchet tied down from the rear frame rail, under the bumper, over the bike rack reciever, then back under the bumper to the frame rail on the other side. I have over 3k miles on this setup over pretty rough expressways (IL) with no damage to anything, carrying 4 bikes. still holding tight. I also have a rear view camera that I can keep an eye on them when I hit bumpy roads.
BTW, I moved my spare to the A-frame to offset some of the weight on the rear from the bikes.

A bad day of camping is
better than a good day at work!
When we bought our camper we sent it to a welder for $75 to weld the hitch bracket onto the frame so it bolts to the bumper but welds to the frame. I'll try to take a picture but it was ell worth it because it don't move one bit!
