Just looked through my dealer's brochure... They have the 250trs and 260trs listed. The MSRP of the 250trs is 34,600, and they have a price of $24,500. Both those numbers are within $200 of the prices listed for my unit.
With that in mind, and knowing I had several other dealers quote me prices on mine, I'd say anything below $23k is a good price. A target of $22,300 (like mine) would not be uunreasonable.
For a comparison, call my dealer, located in central PA Lerch RV 800-722-1236. They can give you a price, which will let you know how your dealer compares.
