Regarding the possibility to switch the document class with
prdefault.cfg or prauctex.cfg I am at a loss as well.  Maybe David knows
something about it.  But I think something like this would be a bit
fragile anyway because the "original" document class might redefine
LaTeX constructs which would be displayed incorrectly with another class
or certain constructs might not be defined when using another class.

I tried to typeset a small sample file using thuthesis.cls from CTAN in
order to find out what exactly is causing trouble.  Unfortunately the
class requires too many packages I don't have and cannot install on the
computer I am using at the moment.  So I'm sorry to say that I am a bit
at a loss with this route as well.  I might have another stab at it once
I have my own computer back.
