Hey Madman. Being a former Certified Raymond tech, I can honestly say that we had to be re-certifed by factory exam every 3 years after passing the level II test. As for can bus communication, Raymond has been using it for years. Now instead of power card, sytem card, vfc card, carriage control card, etc., you only have a couple of power amps and a vehicle manager (and carriage control card on OPs). I took care of a very large customer (approx. 200 pcs. of equipment) for many years. They were a diverse mixture of brands but I still found the Raymond (and Mitsi/Raymonds) easier to repair and more dependable. Where I work now we have a fleet of 98 with 55 of them Raymonds. As long as the maintenance (my job) is kept up, the only breakdowns I see is due to age and operator error.
