We have gps.Its ok you dont realy see any savings if you have good techs.When Im on the road I cover my time.If im on a job and it isnt done at 12 I dont stop for lunch.I used to spend more time stoping in on customers in the area just as a checkup.Slow day on the way back stop in say hi is all doing well then move on with GPS I dont do that anymore.Lost sales over that.If your there and they think that a travel fee wont be charged they might say I got a oil leak, a miss ect.Also let them know you were on the job looking out for them not hanging around shooting the fat just a checkup.Also Gps in any form can be bypassed.Check the net truckers do it all the time.You will save some if you have techs that cut the clock,take longer on simple jobs spank service ect.Paperwork always tells on them.A service was just done now the carriage is falling out How do you miss that on a service?If your seeing that it needs to be took care of because it will also ruin a good tech if he sees everyone else is not doing crap and I have to go back and fix what they dont want to.You always burn the go to man out dont we?Go fix this go see why that.Then they get to a customer that they normaly dont do only to find a tech was there and serviced truck a week ago.Fan belts broke,Carrage bushings shot,No lube on kingpins.Gps wont fix that they just spend more time goofing off at customers location.Regular inspection of all service techs work and customer feed back is the only way to save money and fuel cost.If you do your homework it pays off.Will it **** a good tech off to have his work checked.I dont think so.I welcome new eyes on my trucks because im only a man.I miss stuff to.We can all learn, its just when you have people who are only ther for 8hrs then home you will find waste.Now that wont count on anyone here because you took the time to learn more off the clock didnt you?Soap box can now be taken I feel so much better.Wait I have to go to work today I feel worse
