Who's operating their business with a defined trade cycle for their tractor and/or trailer? One definition of a defined trade cycle would be every 4 years/500k miles. If you're running on a defined cycle are you purchasing new equipment?
Personally I've always went (and will) go new. NEVER had any of the highly talked about mechanical problems!! NEVER!! That includes 2 Acert powered tractors and my current 2012 DD15. My trade cycle averages 4.5 years/500K miles.
In my operation reliability rules!! New equipment (and my experience) has proven the best guarantee for reliability. Many companies of all sizes are set up on a regular trade cycle. Most of them are still in business too. Yeah, I get it why companies may opt for new equipment......driver retention, neglected maintenance etc. The way I see it is simple......do what the successful companies do. Perhaps the fact that I serve my own direct shipper/customer base plays into my decision as well.
Bring on the firestorm........
