We have 2014 Windjammer and no regrets. Only diff between Flagstaff and Windjammers are interior decor and decals outside. Find the cosmetic that most suits you and order. Other than that all else identical...made on same assembly line by same workers. I was told the reason they do Flagstaff and Rockwood slight differences is so that dealers in same town would not compete.
Ditto in the Trail Express aka "Trail Exlploder" tires. Prioritize this as one of your first upgrades.
