  It's really sad that with a name as reputable as Cummins that this service shop can put the Cummins name on the front of their building! My motorhome sat at this shop for just shy of 2 months. I requested the fuel filter, fuel separator, air dryer filter, and air filter be changed. I requested a radiator flush, and also requested the generator checked out, although I didn't expect any issues as it only has 215 hours on it. Every now and then there's a small drip of oil on my driveway after a long drive. I asked them to see if they could determine where this is coming from, and if it should be a concern. They were also to grease/lube the chassis. Apparently this facility is so antiquated (according to Bill) that it can't accommodate a motorhome the size of mine. It's only 43' long. However, this is supposedly the reason they had the unit for almost 2 months, they didn't have a bay available to lift and grease the chassis. The unit sat for so long that the chassis battery ran down and it seems as though I paid a diesel mechanic $160/hr to charge my batteries that ran down due to their incompetence. Every day they worked on it, the mechanic notated in his "diary" (which you get to read on your invoice print out) how the batteries ran down and he had to charge them (the batteries are less than a year old). In the end, I paid $398 for parts, and $1600 in labor to be told my generator is in fine condition, and they weren't able to find any oil leaks. After sitting outside in the sun for almost 2 months and $2200 out of pocket, I've got a flushed radiator, new air, fuel filter/fuel separator, air dryer filter, and a greased chassis. I will be looking for Cummins service somewhere else other than STL. The Fenton location works on generators, but they're not equipped to work on main engines, the Hall Street location works on larger engines but apparently their facility is so antiquated it's worthless. Don't bother going here especially with a motorhome....very disappointing and expensive for what you get!
