Back in late 2003 we were looking at new and used rigs. We ended up buying our Tioga 26Q for cash for around $60K after some lengthy haggling with the salesman, sales manager, and closer at a large Socal RV dealership. Buying a new rig has a few "cons", slow dealer service department fixes of factory defects and minor upgrades. There are some "pros" like new unused RV queen mattress and new smell, factory warranties on appliances, etc. and chassis.
Don't buy the extended warranty, it's full of loopholes and doesn't come into affect until housebox and chassis warranties expire. There are taxes and other expenses to buying a new rig that you may want to consider in making a decision to buy new vs nearly new as well as current market trends.
