I know I answered about using RVIA and TL - however they should be considered a last resort. However it appears that both your first line (the dealer) and second (the mfg) have already failed. Could you perhaps outline the nature of the problems you are having?
I would try both the dealer and starcraft again - perhaps you got the wrong person on a bad day. I am amazed at how many different answers you can get to the same question depending on who you get on the other end. Keep a log of when you call and who you talked to.
The finance CO has a somewhat vested interest in your unit and its problems - after all they hold the title. While it may not hurt to contact them - I don't see where they would want to help - again alot depends on the nature of your problem.
