We bought our first TT (X23B) from RV Direct. We had a good experience. never needed dealer warranty service. Some dealers will not service a rig bought elsewhere. I expect your salesperson doesn't want to price match. Their general discount is 30% and some buyers use that as a negotiation tool.
The downside is there aren't many pickup locations (they are regular brick n stick RV dealers) so you may have to travel a bit for pickup and getting warranty, service may be an issue. We went from Houston to Orlando to get ours, made a mini vacation out of it.
