Hired Drivers/Management, New Trucks, Income, Offices, & Related Questions.

Hello

I'm playing R'n'R since 2 weeks and I have several questions to ask.
I'm using the "german" version.
I will try to devide it into chapters.
And i don't use NOS. I don't like it.

1. Rigs and Driving
Okay, the best Rig in game is the truck you like most. Mine is the hercules atlas.

But i don't understand the fuel consumption of the trucks.
I was pulling a 19tons steamroller from LA to Burney. On the hole way i only needed 347gallons of diesel. I have filled my truck up in LA, drove to Burney, deliver the Steamroller and drive to the next gas station. 347 gallons.
In Burney i took 2 containers of wine back to LA, 8tons. And i got to refuel my Truck at the Truckstop near by Lebec. 356 gallons.
Both ways with ctrl+forward.
I pull a heavy cargo up the hills and need less fuel then pulling a light cargo down the hill?

Is the CP600 engine a gascuzzler? I've got the feeling that the CP600 need about 15% more fuel than the DDS575.

Is their a possibility to modify the gearboxes? In several trucks, like the Argosy or the classic, the gearbox has a really long transmission. The Argosy could probably go 135mph in the 5th gear. Even without a trailer and driving dowhill with CTRL+forward and full NOS, i can't reach 130mph.
The Atlas has only 475HP but a really short gearbox and i think, its the fastest rig ingame.

2. Weather
Wuhi, the sun always shine in california. California the sunshine-state.
Where???? I'm always driving in the rain or at least on wet streets.
The weatherreport in my pda says sunshine and it is raining cats and dogs. Everwhere. Only in a small area around oxnard i have dry streets and sunshine.
And driving on wet streets is unfunny.
Is there an option i don't see to make the weather more californialike?

3. Management
I just don't understand my driver. What in hell they want?
I have a rank 907 driver that earns 2250$/d and has a loyalty of 63% and a daylie income of about 9000$.
My other two drivers are crazy. Rank 868 and 827. If i pay them in the auto-option, they will earn 2973$ and 3298$ per day. With a loyalty of 37%. And both have better trucks than the rank 907 driver. And their daylie income is 6500$ and 5700$.
If i pay them 2250$/d, they quit immediately.

Maybe you could gave me some answers. Especially on chapter 3.
