Rear “bumper “ strength?

I have a 2019 Keystone 302FWRK 5th wheel. It has the spare tire mounted and I would like to add a clamp on 2” receiver to carry a carry rack.
Anyone know weight rating for “poop pipe” container?

It's all about the strength of the brackets that hold the square tube to the framing of the trailer. I've seen them broken from just the weight of a spare tire.

Don’t hang bikes of of it the steel is thin and weak . Bouncing of the trailers in the rear makes it worse .

Since it is newish know that bolting or welding anything to the bumper and or the frame can void the frame warranty. Factory bumpers are typically only rated for 100-150 lbs. If it is hanging on a receiver hitch it will be less than that. My fifth wheel was out of warranty so I added Safety struts and welded in some gussets. I carried 300 lbs with no problem on a bolt on receiver.

Simplest solution would be to wait until the warranty runs out, then have a =good= welding shop add a completely new rear tube and any extra bracing / plating to support whatever load you want to carry. On my old Komfort, my shop found a tube that was much heavier but was the same OD as the old tube. Welded it onto the existing frame extensions and was able to re-rivet the polished aluminum sleeve over it, which was nice. Because the ID was smaller, none of my stinky hoses would fit inside, which I didn't care about since I carry them looped together in a milk crate. Oh, the reason I added the new bumper was to be able to put a 2" receiver on the back for a bike rack, though the shop said I'd be good to 200 lbs if I did want to put a rack on it. Funny, though; the LCI rack on my KZ, which is anchored to both frame rails, is only rated to 200 lbs. I guess LCI doesn't trust their own construction to give such a beefy-looking rack such an anemic rating. :-/
