Bike rack for class B

[Nike]

I have a Yakima TwoTimer for 2 bikes and would like advice on whether that is safe for a Class B Winnebago Era. I have read that some bike racks cannot endure the bouncing of the rear of a motorhome. Any experiences to share?
Thanks.

I have a Saris 2 place rack that is very similar to yours, I use it on the back and occasionally on the front of my Class C.

Mine uses a bolt instead of a hitch pin to really make it tight in the receiver so it doesn't rattle around or move back and forth in the receiver.

I also use one of these to make sure it's good and tight. This thing removes all play in the receiver.

I use the same type of hitch tightener on my class A.
It works great, makes the bike rack VERY solid on the back of the RV.
