Armadillo trailers used to make a 1900 pound model. Not sure now.
There is also the alto safari trailers. Seems to me there is one in that 1700 to 2100 pound area that a lot of the electric vehicles are pulling.
And T@B makes the 320 which is like 1950 dry. Also really popular with the Tesla crowd. We looked at one of those. Pretty nice. Good bathroom and kitchen. Table folds down to a bed but it’s a big bed and many just leave it set up that way. Pretty liveable for a 1900 pound trailer. And not crazy priced. Wet weight would probably around 2400 pounds max. The Subaru should be fine with that.
We tow its big brother the T@B400 but it’s too big for the Subaru. Great build quality though. And not a glitch after pulling it 15200 kilometres this year.
