13 without roof A/C (7'6") will fit in your garage as well. Not as nicely finished, perhaps, as the Outback, but as far as I know they are able to deliver them as promised.
But not for this summer. I'm guessing orders now are for late fall
or winter delivery. I seriously doubt Outback is going to get you into a new trailer for this summer, either.
Have you checked out Relic trailers
? They will also fit in your garage (7'4") and it looks like their only dealer, Floyd's RV in Norman, OK
, has a few finished units in stock ready to go. Long way from BC, though! I don't know how long it might take to get one directly from the manufacturer in WA.
If you really want something for this summer, used is another option. Even that won't be easy as demand for the little eggs is pretty high.
