Granted, we are biased but we will throw in our 2 cents. Outback is a great product, but you might click on this link and then consider these items:
Keystone Outback | Floorplans
The LaCrosse has upgraded kitchen countertops.
The LaCrosse has a pantry beside the refrigerator.
The radius bath wall on LaCrosse is a nice touch vs. the square wall.
There is a pot and pan drawer under the stove vs. the converter - see their gallery.
There is a pot and pan drawer under the refrigerator vs. the furnace - see gallery.
We have a window at the dinette end wall - see gallery.
The entertainment center is upgraded and has a larger TV.
LaCrosse has wooden close-off doors into the bedroom.
The Toy Box in the LaCrosse bunk room is a nice add-on.
The LaCrosse has Slam Latch Baggage Doors, Electric Jacks, and an Exterior Convenience Center.
The LaCrosse Outdoor Kitchen is considerably nicer "looking" with the stone facade.
Best of luck and hope to see your name on Gary's PT Crew List soon!
