What’s my 2019 Flagstaff 21DS worth.

[Csbadvisor]

Where do you research retail and trade value for used TT. Own a 2019 Flagstaff 21DS. Purchased new 8/19, been out 4 times. Like Flagstaff and Micro Lites and looking to move up to 25fks. We determined separate bedroom is a must have. Appreciate any advice
Thanks

Start with NADA and RV Trader.
With NADA, you don't add value for so-called "forced" option packages. These are packages that you have to accept. They often include 13.5k a/c, vent fans, power tongue jack, furnace, tv and so on. Only add value for true options, like slide toppers, thermopane windows, theater seating, upgraded 15k a/c and so on.
