This is my first post.  I am a new member.  An RV repairman told me that my 1992 Beaver Baronet parts are hard to get and he would not work on my coach.  Is this a correct statement?  It has 140,000 miles.  I've kept it up mechanically.  I want to take it out for a few months.  Will I be able to find someone to work on it and get the parts without it being cost prohibitive?  I live in Scottsdale, AZ.  
Thank you for your reply.
