Depends what I'm renting. We have a couple of large equipment rental companies in my area. The ones I choose are not necessarily based on price, but on service and equipment condition. The company I prefer mini ex's/larger skidsteers, keeps their equipment is condition to be sold at any time. When I did have a problem with them on one occasion, they came out right away ad swapped the machine for another one to lower our down time. We were down a machine for about 3 hrs all together, on a 2 week rental. They knocked 15% off the rental bill for those 3 hours, even though we still put over 80 hrs on the machines. Thats good service.
Why do people not respect us as they do other tradesmen? Because every Tom, Dick, and Harry doesn't think he can be a plumber or electrician!
