Correct...all our drive bases since 2008 have been made out of 0.060" 5052 AL.
Other than some bashed in corners, we've had no issues with strength or flex. Well, except for when we fell off the top of the tower with our practice bot...directly onto the front of the frame. One side was 0.5" shorter than the other.
All our panels are designed with a 1" flanged on top and bottom. Then we design in a "mid-plate" somewhere (depending on packaging) in the chassis to help tie the right and left side together. We usually cut our some additional gusset plates for any corner that didn't have one designed in.
We typically tie in the other subsystems (shooter, lift, arm, etc..) of the robot into the frame with 1", 1.5", or 2" - 1/16" wall AL tubing so that it's all rigidly assembled into the frame.
