The physical tank capacity of about 35.000 lbs is correct. The flight planner however has a max trip length limit of 2000 nm. In real the theoretical limit is about 2800 nm. But offcourse everything depends on your landing weight (ZFW+reserves), wind, cost index, etc.
Here is a table that goes to 2800 nm
SMP/RWC runs fine with 10.50. If you're running into performance problems, I'd suggest resetting your SMP configuration settings to start from a known good configuration, and then turn up the cloud draw area while you're in stormy conditions until performance is no longer acceptable in order to find the sweet spot for your system.
No, I fly full time. But I have a nice gaming-laptop that fits just inside my flightkit and since I am old and married, I don´t have to entertain the flight-attendants and hit the bars during night-stops anymore, I actually get a lot of stuff done .
