Ideas for solar generator placement

I am looking for ideas of where to place a Bluetti AC200 that i just purchased. It hasn't arrived yet, but i wanted to see if anyone had already placed a solar generator or extra battery system in the bed of the truck or even cab.
My main goal is functionality. It needs to be easy to get to, but out of the way when not needed. Also, removable when i want to place it somewhere else at my campsite.
I just purchased a Dometic fridge/cooler and am waiting on a fridge slide for it. That will be installed in the bed against the tailgate just right of the center of the bed. Up against the right wall, between the fridge and the edge of the bed, i have a WaterPort installed.
How do others with fridges that take up bed space make this work? Behind it?
I'd like to keep the left side free for gear that i can put into rolling containers and slide into the back of the bed.
