Just sold my 2004 Travel Supreme 45DSO4 and purchased a 2015 American Eagle.
The Eagle is the second from the top of the line in the American Lineup and the Dream is the third from the top of the line.
We really like the full wall slide and newer systems in the Eagle.
A real downside is the black tank is only 40 gal vs 60+ in the TS.
The Eagle is on a freightliner chassis vs the Spartan for TS (not sure that really matters)
Th fit and finish of the Eagle is of decent quality but it isn't near the quality of the TS and certainly the cabinetry isn't anywhere near the quality of the TS.
Have had good luck and responses to questions about operation on the Facebook American Coach website and in talking to other American owners they are all happy with service, parts availability, and Freightliner.
We really like the Eagle but if there were a 2015 TS with this layout and a full wall slide we would hands down go with TS.
We looked at several Entegras, Newmars, and Tiffins inthe same model year and by far liked the American product line the best.
No reason not to buy an American if you like it but it isn't in the same league with TS. Just my opinion
