The single center mount of the cargo rack , allows the rack to rock side to side ; WITH EVERY BUMP IN THE ROAD ; eventually , the rack will start to flex tearing apart the welds , or more correctly the metal next to the welds , and if not noticed the rack and contents can drop on the road.
Have a look at the factory slide out racks that are an option on some 5ers, they appear to be built to last.
Also , any weigh added behind the rear bumper on a trailer , lowers your pin weight , any pin weigh reduction below 15 % of the total loaded weight on a 5er, will effect handling , in ways you'd rather not experience.
( Don't ask how I know this. )

I agree... I'm mounting a storage, generator, bike rack, skid plates, leveling jacks to the back of our 5th. I'll have a pcs of 1/4" x 5" steel tube welded to each frame rail. The tube will extend 18" out past the frame/bumper with 4' welded to the frame and it will be cross braced.

Last 5th wheel (Alpenlite 25) had a well built rack welded to the frame when I purchased. I installed a 250# genny, 12 gallon gas tank, small gas grill and a plastic tool box that held the gen battery and a few wooden leveling blocks.
Might have had 500# total, plus the weight of the rack itself. Coming south through Mississippi last summer, the interstates were so rough that the hard bouncing actually bent the frame behind the axles enough that the siding on the back of the camper separated about 2". Be careful how much you cantilever back there! Probably better off w/a swivel wheel.
