Question Anyone know the carrying weight capacity of a 4' bumper Rookwood Signature Ultra Lite?

Pardon me if I posted this in the wrong area. I'm new to this forum.

I have a 2015 Rockwood Signature Ultra Light FW (8280ws). It has the 4' rear bumper that carries my spare tire. I would like to install the Curt RV Bumper 2" Trailer Hitch Receiver E-100 and use that to install a bicycle rack. (That receiver attaches to the bumper as opposed to one that attaches to the frame). I prefer the 2' hitch so I can use the same bike rack on my truck as apposed to the 4' clamp on bike rack which would only be used on the FW. I have no intentions of towing anything.

Does anyone know what the limits are of the 4' square bumper?

Thanks for your help!!

You should do a search for this topic as you will get answers from 0 lbs don't do it to I have done it with no problems.
My personal opinion ( that Costs you $0 and is worth every penny) is the ultralight bumpers are not strong enough to handle the forces a bike rack puts on the bumper.

The key thing to understand here is the term ultra lite. It means much more that light weight. It also refers to the frame composition. Most if not all ultra lite RVs use a manufactured I-beam frame meaning three pieces of steel are welded together to form an I beam. This results in a lighter frame but also less strength. The limiting factor here is not the bumper itself, but the frame. The torque of a bike carrier on the bumper could damage the frame. In addition, the carrier is less stable and will move around a lot and possibly damage your bikes. You will find people who do it, but that in itself doesn't make it right. Check the bumper if new unit, it should have a sticker with the weight limit.

PLEASE do a search here on bike racks.
There are thousands of posts about what you're asking about.
FR was putting stickers on ultralight bumpers, warning that any modification to the bumper would void the frame warranty.

I agree with the above posts as you will get many opinions from others. One thing I did to lighten the bumper so that I could carry other items is move the spare tire under the front frame behind the front jacks. You can use a truck style crank-up holder with a cable for the tire mount. My dealer carried them. You can also do a search here and find more information. Once the warranty is over, I will have a regular receiver hitch welded to the frame which takes the weight off of the bumper.

Thanks for the info! Seems like the thing to do is the frame hitch. I guess I knew that really was the correct thing to do, just thinking I could save a little if I could get away with a bumper hitch!

I started a thread here a couple of years ago stating that I wasn't afraid of heresay & I was going to go ahead & install a bike rack on my bumper. By the time my forum friends had posted stories & pictures I was pretty much convinced it wasn't just heresay. Needless to say I still carry 2 bikes in the trailer...

Visited factory where windjammers and v lites are built. Engineer who showed us models we wanted to see said that bumper are built to handle bracket and weight of spare, about 70 #. Remove spare add bike up to that weight. He was proud of what they were building there!

Thanks for the replies!!

I've been doing a search on "Bike rack" ( like many of you suggested ) and see all the different solutions although it's seems like the real solution is to attach the hitch to the frame.

Seems like that's the way to go!

Now to figure out the warranty issues that may cause.

Thanks everybody!!
