You might be able to squeeze 2000 pts. out of it but I don't believe it would be very competitive. There are 108 Orks and only 2 fragile trukks that can transport a maximum of 24 Orks total. You need 5 burnas or 5 lootas to make a mob of each. To be honest the list as it is would probably be rendered ineffective before it reached combat. :no:
