I am at the 3 day seminars put on at Okanagan College in Kelowna BC, Canada. There are held 3rd weeeknd in June and are well worth it, BTW.
I have found out this, a similar facility in Alberta and a smaller one in Florida are the only places in North America for properly training RV technicians. Apart from that there are 3 online courses in the US and a few 5 - 7 day training course. That's it. The RV tech course here is 6 months long
There is no way you can train an RV tech 5 days, anymore than than you can turn out an auto mechanic in 5 days. It explains some of the quality of work I have had done on mine.
It's surpirsing considering the size of the industry, I am guessing most RV techs learn on the job, not spend 1/2 a year in school then go to on the job training. A lot probably come from assembly plant jobs. It explains the butcher job by the dealer on my new RV after I picked it up. (RV Peddlar in Bakersfield who just went bankrupt) It's a real eye opener. I always assumed RV techs were like auto mechanics, they had been to vocational school, then served an apprenticeship. That does not appear to the the case in the RV industry,its a real eye opener. I am spending 3 days here in fairly intense seminars. At best I will be able to have an intelligent conversation with an RV tech. When I see schools advertising how to become an RV tech in 5 days, like this link https://rvtechcourse.com/ it's scary.
