Yeah I know what your saying. I like the looks of it there and how it kinda boxes the cargo in but it does wobble/bounce with me pushing on it.
I will try welding a gusset in the back of the angle and see if it stiffens it up. If not it's gonna go under the camper (towards the front) or in the front under the bed.

Someone has to say it; please keep an eye on your frame and sidewalls.
Might be a good idea to take it for a spin loaded up with the DW driving and you following in a car to see how much frame flex you experience.
Remember; no shocks on the camper. There will be a lot of up and down movement in any case so make sure to tarp the entire load and tie it off good or some of your stuff may get left on the highway.
Monitor every month (initially a season or 2), just behind the rear axle attachment points and at your bolt holes for frame cracks; then semi-annually thereafter.
The increased flexing of the frame due to the increased length will shorten frame life; how much is anyone's guess. The point of maximum stress is right aft of the rear axle.
Additionally, wall flex as a result of frame flex can cause cracks at wall openings. Any sign of cracks in penetration corners (slide openings, doors, hatches, and windows) is cause for concern.
Look out for signs like this.
