Nope. But then I don't expect a fast analysis. Typically the detailed
analysis that I get back takes weeks (sometimes months) and often doesn't
give me any more information than we have right now. That's because in most
cases it's really tough to determine the root cause in something as unique
as our GMCs (by now each one is unique from an electrical standpoint -
different resistances etc).
Based on the facts that we know so far, it's pretty likely that your MOSFET
just gave up the ghost without any unusual external events. So it wasn't
your fault. And it probably wasn't anything in your coach. Put your new one
in and see how it goes. IF it fries agains, then there is something about
your configuration that the Truecharge doesn't like. But, with 50+ hours on
your unit I doubt that is a problem.

Have patience now. Statpower is highly motivated to discover any conditions
under which their units may fail. If they can design a solution to stop the
failures then they come out ahead. If they have to warn customers about
special conditions they're still ahead.
I'll see where QA goes with your unit. If necessary, I'll offer to sign a
non-disclosure agreement with Statpower to allow me to talk about actual
failure rates and mechanisms. Then the best that I could tell you all is
"no unusual failures reported." My sense is that we'll get more information
from QA that will allow us to make a determination about TrueCharge in teh
GMC without any special steps.
Expect an update from me about every 3-5 business days.
