Hello! Newb question here about $20k-30k 5th wheel

Sounds like you have a 2500, if so pin weight will be your limiting factor. Look at loaded weights, not just dry. You’ll probably run out of payload long before you get to the 17k towing capability. As others have said, you’ll get much more for your $ if you can fall in love with a used model. If stuck on brand new, know that you should end up paying 20-40% less than MSRP depending on many factors.
Good luck
