Hitch Install/Rear Mounted Gas Tank

[Nitroblood]

Hello fellow Chevy/GMC Truckers, it's been a veeerrry long time since I last posted. I've finally got my big boy C20 going, and running strong.

I plan on using it to pull a trailer, hauling a car or dump trailer. However, I also plan on installing a rear mounted gas tank.

Are there any issues with our trucks having BOTH installed, since they're essentially using the same frame space? Pros/Cons? Safety concerns?
*Any feedback is greatly appreciated.*

I know the SEARCH is an option, I'm just trying to use up some of my, "our", CoronaV time
