Cooper is an old name in mobile drilling, and the TL550 Mobile Servicing Rig is one reason why. Once a well is tapped it needs lots of work and this rig can service 2 1/2" pipe nearly four miles into the ground. One of the best features of the sweet Cooper is the uncovered 550 HP Detroit Diesel engine. Covering the power-source in this case would just add heat and make it harder to service. Also, it just looks awesome.
