So, assuming those campers are somewhat level, the carriers already show signs of impending trouble (significant down bend).
I doubt they installed them "unlevel" like that. Additionally, they are fairly new campers and may not have seen much road use yet.
Like any overstress, one or three times may not be the "charm."
The "Charm" none the less will most likely happen; typically without the owner's awareness until it is all over but the crying.
No vested interest here; and you, of course, can do as you will with your camper and expensive equipment/bikes in "hacked on" storage.
I would feel remiss if I didn't give you fair warning that this could be troublesome.
