Presented by increasing size:
42001 Mini Off Roader
It keeps the orange color theme and seems a cheaper way to have the new micropanels.
42005 Monster Truck
Interesting piece count, panels, balljoints and the best trialtruck wheels.
42008 Service Truck
This is the return of the green, it seems the most interesting set of this season due to piece count, the great number and variety of the rare green panels and the pneumatic functions combined with linear actuators.
The secondary B-model seems interesting too.
42009 Mobile Crane MK II
Yes, another crane, personally i prefer the b model so much, a container handler:
