Nice employees, but over-rated and expensive. My RV fan belt broke on a Sunday night, worst time to get help. Had to get towed to Clarke Power Services in Wentzville, MO. They added $50+ to the tow invoice and said it took 3 hours to replace the belt in a Cummings diesel...ridiculous! I had just purchased this and drove it for about an hour, everything worked fine. When I picked the vehicle up, the side mirror would not adjust from the electric control, I disregarded it and drove home. The next time I stared the RV the mirror fell completely into the arm and pieces of plastic bushing came falling out. I called and the service manager was very nice, but no one could tell me why the mirror was broken. It worked fine prior to their service. I was quoted over $1600 for brakes on Rockwell axles and a second opinion from another repair shop quoted me $1000. Just hope you don't break down in Wentzville, MO...this place will overcharge and break your stuff too!
