I have a 2017 Bigfoot
25RQ that I'm just about to list on this forum for $49,500. It is, of course, 25' long and you are looking for a 21 footer. However, if you think you are interested in my trailer, let me know and I'll send you some pictures. It is in very good condition and everything works as expected. I live just south of Nashville, TN.
I'll get the ad up on this site as soon as I can learn how, and I'll post some pictures then. Smiles and Happy New Year.
