I would also vote for Newmar. Either of those manufacturers make good coaches but I believe the Dutchstar (and all models above that) have side radiators vs. every DP made by Winnebago has rear radiators. Now some folks may not think that is much of an issue but it is when you have to service stuff like belts, alternators, water pumps, etc. The side radiators provide much better service access and that may cost you less in labor costs over the life of the coach.
Also, side radiator coaches do not crud up the radiator/charge air cooler like rear radiator coaches do. Another potential advantage with Newmar is they use a 'hung-wall' style of wall construction vs. Winnebago's vacuum bonded walls. In the case of a water leak that goes undetected for some time, a vacuum bonded wall can delaminate where it is said that a hung wall cannot.
Just things to consider. Not show stoppers either way but things to consider.
