We have a Forest River Lexi we just bought and also bought a 2013 Subi Crosstrek to use as my daily driver ane to use as a toad. It's our 6th Subaru. Choose it because of it's relibality, it only weighs around 3100 lbs, is all wheel drive, and will go just about anywhere a stock Jeep will go as far as trails.
Haven't towed it yet as still waiting on baseplate comming from Blue Ox. They have a dedicated baseplate for the Crosstrek. Will be using a Ready Brake system on mine.
There is a forum, SubaruXVForum.com, for Crosstrek's, and several members have set them up for towing with no problems. On another forum, clubcrosstrek.com, a member, CJBROWN posted his setup and photo's in a thread, "setting up the crosstrek for towing".
Just make sure that you get the standard 5 speed stick shift as it can be flat towed. Just put it in neutral, turn the ignition to unlock the wheels, and go. The auto tranny cannot be towed at all...
