I do not know the Snoozy, but I will give another thumbs up for the NuWa T@B 320. While not for me that small, but I have a friend who has one, as it is just her and her little dog that goes camping. She is a member of the Sisters on the Fly organization and goes by herself with it. Hers, I think, is about three years old, and I do not recall if the back of it opened into a kitchen. It may have been just storage back there at the bottom.
I have seen it up close, inside and out. It is a well-built camper compared to many of the larger camper builders. The 320 you can stand up in it, (I'm 6 ft) has a shower and bath, inside cooking, and a larger bed option. I was impressed at the detail-level quality inside and out. It is a cute camper.
As for towing, she tried to tow it with her Chevy Equinox, and it did not do well. Not sure what engine it had. She traded the car for a Toyota Highlander with 5,000# towing capability, and it solved all her problems.
2022, 320 is rated at 2,900# GVWR. While they may not fill it full, just a heads up, being up against a 3,000# tow rating of the Subaru may not be a fun towing experience as time goes on and more stuff finds its way into the camper to fill it. Including the loaded tongue weight with no WD hitch. Plus, the cargo weight in the car. My friend lives and camps mainly in PA and Maine. Both have good-sized east coast hills/mountains to climb.
Hope this helps
