After much research & reading multiple threads re: luggage on FT,
ACCDraw.2 was torn between Tumi and Briggs & Riley. B&R was having
a sale, that settled it - ACCDraw.2 bought one & is crazy about it.
The only time it's been gate-checked has been on a CRJ700.
It seems most, if not all carry-ons are gate checked on those 'lil guys.
