Rear bumper addition

My Chaparral 390 was one of 2 Chaparrals that doesn't come with a bike rack mounted on the rear bumper. I suspect being over 42 ft may be the reason.

But there are 2 stickers on the rear that contradict each other. This one says mounting anything on the bumper is prohibited and may void the warranty.


And this one says what ever I mount on the bumper can't exceed 135 lbs or 24 inches.



I would like to put a bike rack on the rear.

Thoughts?

Don't do it. In the last two years I've seen two bumpers fail and bikes damaged. I put a Curt front mount hitch on my truck and use a Swagman XC bike rack. Solid as a rock, easy to install and I can keep my eyes on our bikes.

This post will certainly start a debate. I lost a bike doing the bumper thing. The forces exerted on the bumper from a bike bouncing ( regardless of how secure it is) may damage the bike/ bumper and/or frame...yes the frame of the camper

I got a big hole in the back of my camper when I put a bike rack and bikes on it.
Bikes bounced so violently on the flimsy bumper that one of the handle bars went right through the back of the camper.
Run from this idea.

Thanks everyone. I really don't like the idea of it hanging out back where I can't see it anyway. I have a very expensive road bike ($5,000+). I had a fork mount that I put in the bed of my truck right against the cab, but I added an auxiliary fuel tank in the bed and that took my bike space.

The factory rack looks fairly robust and mounts to the frame rails and not the bumper. The frame doesn't extend as far on my 390 as in this pic though.



Looks like I go with my old option of putting it in the 5er. Keeps it out of the weather that way too.

Interesting, because my Crusader came with a Grill, Swing Extension Arm and tire on a steel rim that weight the amount on your second sticker of 135 lbs. That grill bounce up down by about 12 inches going down the road. I took all that off and put on a bike rack and 2 bike that weight 95 lbs and didn't bounce near as much as the grill. If I had the sticker I won't put anything on the bumper that would void the warranty but after the warranty I would contact Lippert that makes the frame on your 5er and get their advice on installing one of the hitches they have on their website.

Here is the website of the people that made, designed, and test your frame and the hitches they designed to go on it...

I ran into the same problem. Our 370 fl couldn't get the rack. I'm having the dealer put a 2" receiver on it for a bike rack
I'm going to miss that rack.450 # wieght limit. Had the genny and a 4' tool box on it.

CWSWine,

Thanks for the Lippert link. That lists the bike rack that mounts to the frame rails that is standard on the shorter Chaparrals. I'll contact them about the install specs to see if I have enough frame rail to mount it.

If you look closely,the gwo rear frames are not alike. Ours on our short Chapy is much beefier where it comes out for the rack. Much different on the longer Chapy.
We were told from the factory rep that it couldn't be added.YMMV.
