These are the differences I see and by far, the Newmar is the best-looking. It is bright and has gorgeous cabinets.
Newmar: LOTS more cabinetry , especially upper cabinets across the whole living/dining area; wonderful hall cabinets/drawers and cabinets/drawers at the foot of the bed. The Excursion doesn't have nearly as many cabinets - none in hallway like Newmar's and none at the foot of the bed.
Newmar: Side radiator
Newmar: pass through outside storage - The Excursion has shallow storage.
Newmar: Table and chairs at curbside/patio side. The Excursion has a booth and many folks find them uncomfortable, especially for a larger person.
Newmar: Has a much nicer kitchen with more countertop space.
Newmar: Has nice porcelain sinks in kitchen and vanity. Excursion has stainless steel and looks old-fashioned
I'd definitely vote for Newmar with it's history of satisfied customers. Plus, we full-timed in one for 10 years with no complaints.
