The crawlers were overhauled in 2003 with upgrades to the Motor Control Center, which houses the switchgear and electrical controls of all of major systems on board; a new engine and pump ventilation system; new diesel engine radiators; and replacement of the two driver cabs on each vehicle (one on each end).

In Sid Meier's Alpha Centauri, various units are called "crawlers" and feature chassis based on the crawler-transporters.
