What is your Subie rated to tow- total weight
and tongue weight
? Some of the 13'ers can get quite heavy, especially if they're loaded with bathroom, HW heater, AC, fridge
From other posters, it seems many Subarus are limited to 200 pounds tongue weight
, so that means keeping the trailer weight under 2000 pounds fully loaded, i.e., fairly simple.
If you only have 1 or 2 people, the Hunter Compacts and Trailswest Campsters are among the lightest molded fiberglass trailers, and they have a lower towing profile. The Compact Jr. is narrower, too.
Do you have any preferences regarding budget or condition?
Best wishes on your "egg hunt"!
