I think it depends pup to pup. My roof rated to 200+ lbs as is. And the 120 lb ac unit is just fine. That square you can see in the drawings is there specifically to hold the ac.
I couldn't decide if I should put it here or in the heating / cooling section. Here is my description of the process to install AC in my Popup.

Does include one major blunder. See my response.
Before others comment, yes I confused in-lb with ft-lbs, which probably explains the deformation and the bolt hitting the roof. I'm going to try to see if I can back that off some still tonight and see if I have done in the gasket. But I hoping with only 25 hours it may bounce back. Damn...
I just completed AC installation from scratch into my 2013 Palomino 4102.
This is the story with Lots of Pictures.
When we bought the camper, we lived in Illinois. We mad the conscious decision to save the money on AC and for the few weeks a year it would be too hot, we would just deal with...
We do sausage, slice the brown in the do, then remove. (Can also do onions and peppers at this time. Remove)
Frozen hash brown. Brown them in do. Need some oil.
Then add eggs, once eggs al,oust don throw the sausage and whatever else back in.
There is something wrong with your description. If the AC was rated 240v it would not have worked at 110 at all.
a 14 gauge std 110 extension cord is only raised for 18 amps. So if ac was 20 amps 110 v, not surprising it failed.
Everything arrived in 3 days!!
Looks to be in good condition.
Finally got roof drawing info from palomino.
Now I just need the time and the guts to start cutting.
To the original question, as others have said, tape up the ends. You mAy also have a disconnect elsewhere too.
I actually don't have a battery, I do have electric brakes, and yes if the trailer drops it will only have brakes as long as it stays plugged in. I'll get around to adding a battery...
