hitch receiver mount and bumper strength

I'm planning to install this on my jayco swift SLX 154BH bumper. The trailer a 4x4 bumper.

Robot Check


However, I have read on the review that some RV bumper may not hold up to hold bike rack.

Is that really true ?

I look at mine, and the steel 4x4 bumper looks sturdy enough .
At the most the weight of the bike and the rack is 100 pounds. I just can't imagine steel 4x4 bumper will buckle for that kind of weight.

has anyone install the same hitch receiver on a steel 4x4 bumper and use it for bike rack without any issue ?

Dozens of discussions about this both here and every RV forum. The general opinion is don't do it. There are lots of pictures out there of detached bumpers and dragging bikes. That said some people go ahead and do it, several don't have any issues. I camp with a guy who has used it to haul two bikes for 2 years without issue. Personally I went ahead and had a proper receiver welded on for ~$200.

You manual likely says the bumper is rated for 100lbs. The problem with a bike rack it becomes a lever and creates dynamic forces far in excess of 100lbs.

My advice also would be to have have a hitch welded to the frame. With that said, I had a bumper mounted hitch for several years with no problems. Selecting the correct components is a way to better assure success. Use this bracket, not the one you linked to.
https://www.etrailer.com/RV-Hitch/Curt/E-100.html Curt RV bracket.
Next, mount the bracket off center, this reduces the twisting/lever action on the bumper a bit. I mounted mine a bit to the left side, this also lets you see the bike tires stick out a bit so you can see in your mirror if the bikes are still there.
And last make sure you use the right bike rack, only use this one.

Is the idea of using curt RV bracket the twisting force is applied to larger bumper surface area due to the use of 2 vertical square plates ?
If that is the case, would it better to use this one that way the force is applied to 2 horizontal plates ?

I have tried the one in your link, The Curt brand had less flex. I don't think it matters if it clamps around the vertical or horizontal part of the bumper. The one piece Curt one has less flex and a wider "footprint" on the bumper.

Don't do it. I know on some JayFlights there is an option for a hitch that mounts to the frame. We have one on our trailer and took it down to Florida with only 2 bikes on it. Got to Florida and realized that one of the bike handlebars had struck the camper aluminum 3 times, causing minor dents. The handlebar had to move over 15" to hit the trailer... which it did on at least 3 occasions. Moving 15" back, then slamming back down must cause a LOT of force... and I am sure it would have ripped my bumper off if it had been attached to the bumper.

Don't. I did it for exactly half of my trip last summer. The vibration tore the bumper as we were entering Yellowstone and it dragged for a mile or so until it was discovered. Metal fatigue is the best description. After returning home we welded on new receivers directly to the frame and fixed the bumper. Luckily the bumper stayed attached by a thread and a prayer so we didn't kill someone.

Take a good look at how your bumper is connected to your trailer. It's not on by much.

And I never tell this story without again thanking the two US Marines who stopped on their motorcycles to help me get our gear secured.

I watched a trailer loose 2 bikes, the bike rack as well as the entire bumper on the highway a while back The driver had no idea. but after the big rig behind him drove over his setup and blew a tire it snarled traffic up quiet well.

What about the bike rack mounted to your ladder? Is that safe?

Found this :
https://www.mount-n-lock.com/
The safety struts looks to be the answer to my problem.
However it does not reinforce the entire length of the bumer from left to right.
What if the tear happens in and around the hitch receiver that is away from where the struts are ?
I'm asking the following q to the manufacturer:
"I'm intesrested in your safety strut.
But I have some doubt about how it works. Can you please help me ?
It looks like the struts only reinforce the area where the bumper meets the frame. However, if I put the hitch receiver (bike carrier) in the middle of the bumper, how does the struts prevent the twisting the middle section of the bumper ?
The bumper may still be attached to the frame, but the middle section of the bumper maybe twisted, ripped, or may not be hollow square anymore (hollow circle maybe )? "
