Hello.
First, Im Spanish and I don't know English very well, but I hope to make myself understood.
My suggestion is add more big places in parking of Operation HQ zone.
I think is a good idea beacause I arrive there with double trailer, my trailer occupied a lot and came to bother.
To give you an idea: https://imgur.com/gFORvUc (I send link beacause the image is too big)
You can add something like that: https://imgur.com/F9Visqf
In short, the idea is to add more big parking places.
Have a nice day ?
