Here you can get a closer look at the upper shock mounts used on the rear of both trucks. The single coilover on the short course truck is simply attached in double shear to a pair of plate tabs welded to the chassis. The desert truck incorporates a much beefier upper structure tied in at multiple points on the cage to support the coilover and bypass shocks. In general, all the suspension components are beefier on the Trophy Truck. That's not to say the short-course truck doesn't get slapped around as well. On a congested track, Carl inevitably comes in contact with other drivers and that tends to mean a lot of tire-to-tire contact and impact to the axle and suspension components.
