Do shops ever fix something on the first try?

I recently had a cat 3208t engine replaced by a local bus mechanic. He done the replacement within 4 weeks, putting in a remanufactured engine. When picked up, all gauges worked and never had to go back or ask for anything else. This gent is in his fourties and maintains 70 + diesel buses. And my job was done at a reasonable rate. And an excellent job.

If any fellow rv's need rv service near extreme western NC, use Rick' RV Service in Murphy, N C. Rick, the owner and tech Dusty are excellent rv techs and reasonable rates.
