Bike mount on rear of camper? X18D

Just wondering if anyone else has done this. I'd like to mount a receiver for a bike carrier on the back of our trailer. This was generally a discouraged thing to do on our old popup (and pop ups in general) but our camper has a very heavy unladen tongue weight for the weight of the camper (my thinking is that we are well over the rule of thumb 10-15% of trailer weight for laden tongue weight), so I was thinking this would be a good way to kill two birds with one stone: lighten the tongue and offload the bikes from the car.

It's obvious that the C channel metal bumper on the back is going to be too flimsy to mount anything to, so I was thinking in order to to this they'll have to bolt/weld a carrier to the frame and zip a hole in the bumper for the receiver. Anyone else attempted this?

Geoffdaddy,

I personally haven't added a bike rack to the rear of my TT, but I know many that have and the ones that have supported the racks off the TT or HTT frame (in lieu of just the bumper) seem to have the most long term success.

Great to hear that you are keeping an eye on what's going on with your "loaded" HTT tongue weight, not many folks take this very important element into consideration when loading or modifying their HTT.

Since you are considering adding weight to the rear of a rather lite HTT, you may want to take your loaded TV/HTT to a CAT scale first and find out what your "actual" loaded tongue weight is. The CAT scale information takes all the guess work out...., you may find that you are within the 10%-15% of your loaded HTT weight. At any rate, you will need to confirm the impact of the additional weight of the bike rack/bikes on your HTT tongue at a CAT scale.

Typical CAT Scale visit: https://www.jaycoowners.com/showthread.php?t=3169

Also, for checking tongue weights a Sherline LM-2000 scale is nice to have around, I use mine often: http://www.sherline.com/lm.htm

geoffdaddy-- I just put a tool box on the rear bumper( see pics19h mods in the mods forum)& you are correct the bumper has all it can do to hold the plastics ends on. I would suggest that the bumper be boxed and tied to the rear cross member before adding any thing . Larry

I have the mount that you are talking about on my 22FB, it has a 4" square bumper.
I have not have any issues with it. The bike rack carries 3 bikes, I strap them down to make sure they are not bouncing all over.

Big Jim The problem with the smaller & lighter trailers is they have a real cheap "C" channel bumper which has a problem supporting the paint that's on it. It either has to be boxed & tied to the rear crossmember or replaced it and it's supports with a 4" sq tube like yours. Larry

I talked to my dealer and they don't recommend welding anything to the frame due to warranty issues. That said, I wonder if I could bolt a 4" square tube bumper and get a receiver for that. Any idea where I can buy the tube from?

You probably want to go to a welding shop. You will need to weld brackets at both ends of the last cross member & then to your new 4" sq bumper then the reciever to both. Larry

Geoffdaddy,
I have been thinking of mounting a bike rack to the frame at the rear of my X19H as well (I really wanted to do it). After a lot of research I have decided against it.

First of all, I contacted Jayco and the frame manufacturer. Both advised against it, and both mentioned voiding the frame warranty. See Jayco’s response below.
Next, I went to a local RV welding shop with a very good reputation. The owner looked at my frame, and said it can’t safely be done, he won’t do it. The frame does not support it. (I am sure you can find some shop though who will just do it for the money).

Third: in another forum, I also got very strong advise against doing it. Besides the above, it was mentioned that our ultra light TT’s don’t have shocks. That apparently results in the bikes bouncing excessively back there. One poster reported that a handle bar had gone through the rear of his trailer, and another reported failure of the bike rack itself (weld broke).

Needless to say, I decided against doing it. I really, really wanted to do this as I also feel that my tongue is very heavy. I ended up getting a rack for the bikes to mount above the truck bed, and I will move cargo back into the trailer behind the axle. I made some slight mods to secure it back there.

Hope this helps in your decision making. While this may be fine for other TT’s and 5th wheels, I think our Ultra Light Weights are not made for this. I know this is not what you want to hear, it certainly was not what I expected when researching this topic a few weeks ago. But it makes sense, and the risk is too high IMO. You don’t want to lose the bikes on the highway.

Good luck, and let us know which way you go!

Here is Jayco’s exact response, copy & paste:

Jayco does not recommend attaching anything to the bumper or the frame
of your unit.

Should you decide to have a hitch receiver welded to the frame of this
unit and it causes any type of damage from doing so the warranty will be
voided in the area affected.

Unfortunately, not all units are built to hold a bike rack.

Should you need additional assistance please feel free to contact us.

I figured that would be their advice. I can see the point about the lack of any suspension putting stress on it and the bikes. I have thought another idea would be to stow the bikes inside next to the lavatory on a bike mount I fabricate myself to sit on the floor. That would probably be the next best bet. We've only got the two to worry about right now, and I think it's preferable to adding more weight to our TV.

I agree the camper is light, but man it seems like the tongue is rather heavy. I need to weigh it but dry weight of the camper is supposed to be 3600ish, and the tongue 470. I figure with the battery, spare tire, and a full tank of gas it's got to be nearer to 600 and most of that additional weight is going straight to the tongue.
