Forkbroker, Its intresting that you would say that, I have had pretty good experiences with the 5 and the 7 series. I will say the 6 series was pretty decent, and I have many 7 series with over 20,000 hours running on the original motor and transmission. The 8 series weak link is the Can Bus wiring, teenie tiny go to heck 28 gauge thin strand all over the bundle, numerous weak or intermittant low side ground issues, just like their 7HBW23 jack. Also the steer axles are a little on the under engineered side, beefier components would be better.
