I believe the 2019 Outback can tow 2700# with a tongue weight
limit of 200#. The latter is the limiting factor, since travel trailers require 10-12% tongue weight
for stable (sway-free) towing. So, you need a trailer with a fully loaded weight of 2000# or less. In the world of small molded fiberglass trailers that means a 13'er.
Bath or no-bath is the question. With more than two people, you'll want the no-bath, front bunk version. Since you may have little ones, know that Scamp
does provide a convenient storage compartment under the front bunks for a small porta-potty for nighttime emergencies.
With reasonable attention packing you can keep the loaded weight of a Scamp
13 or similar in the 1500-1700# range. That includes a fridge
and A/C, which you'll probably want in Louisiana and thereabouts, but not a full bath and shower.
is the budget brand, but Happier Camper
, and Armadillo
also make 13'ers with the ability to sleep three. If you shop used, there are also many out-of-production 13'ers that fit the bill at a range of prices. A careful inspection is essential with a used unit (by yourself or a local RV shop).
The A-liner folding trailers are nice, too, but for convenient set-up and take-down (especially in the rain and wind), snugness in bad weather, and resale value, my own opinion is that egg trailers can't be beat!
Best wishes in your "egg hunt"!
