Let see Yale used to sell MBP to Kroger but now it is what band? Large Nationa Accounts aren't stupid - if the truck don't work out and the cost to operate them & down time are excessive, service is non responsive to their needs (in teh customers viewpoint) - then they change. Look at Home Depot, Wal-Mart (here I'm referring to ICE units) they have changed. Lowes is a along time National Account 4 Yale right now - some day they could change - if someone wanted to buy into the account.

Coke Cola (CCE) used to be a Yale that changed for some reason, eh.
Every brand of forklift can point to an account/model that ran many hours past the "norm". I worked for Mitsubishi at a point in time a nation wide trucking company out of Ohio that had hundreds in there fleet found the engines to run over 20,000 in there break bult terminal that run 7/24/365 & the cross hatch on the engine cylinder walls was still visible. Then they went to the 4G63/64 engine - the romance ended & opened teh door to a competitor.
Certainly you would find it difficult to find parts for a 66 year old truck - my doctor is have a hard time to find OEM parts for my 1944 knee - so its a plastic one.
Yale & Hyste have & had extensive National / Major Accounts staff for many years (Hyster & Clark used to have the best NA programs going), right? Or they did then along came 2007. The year I hung up my lift spurs.
Have a great day.
