FYI, I am a tech. In order to even recieve the RT-S Demo, we have to do an online web siminar, and then take a test, and pass it. There are 4 total, and they are done with the 3rd one so far.
1. Overview(mand. for demo)
2. Pre-delivery inspection
3. Electrical part 1(mand. for regular shipments)
4. Electrical part 2
If you went to a dealer, and they had a RT, that means they are doing thier training. The RT is the same base as the GS/RS, it just has a bunch of stuff added to it, and it looks a bit different. So, if the techs have worked on the RS/GS it all relates. I wouldn't be worried about the training. Knowledge comes from touching the machines, and figuring things out for yourself.
I'm sorry if it sounds like I have a bad attitude, but I'm just typing how I talk, and what I know.
