Our first one were SRW and they were not good. They made it to about 170k before UPS crushed them. Most died with a trans failure after 60k of shuttering. They all blew turbo hoses and had counterbalance issues. We had one go into a ditch at 70mph and it had 1800 miles on it. I tried to get the engine but UPS has strict rules with taking one out of service. It got crushed. UPS also learned(again) that sheetmetal does not work well in our system. We had many rear clamshell doors ripped off and bent beyond repair. The side doors always had problems. The 10k oil change was too short for UPS as well. They wanted 15k(PMI) and found that air filters were plugging and sucking them through blowing the turbo/engine. The one I am driving now has been pretty much flawless other than normal maint. needs. This one has 124k. Remember though if you want to test toughness put them in a UPS truck. Not much looks very good after 6 monthes on a route. I mean everything gets beat or breaks. I cant wait to see how long our new telemetrics lasts. That is the new "Eye In Sky" that takes GPS to a new level. They can now get into the vehicle computer and watch everything we do. Backing distance, idle time, bulkhead door, speed, seatbelt, throttle position all can be watched from afar.
