I also use a Burley Nomad behind my Catrike Expedition. It holds up to 100 lbs (really, it does!) and with the optional carrier you can take a ridiculous amount of gear with you...more than you'll want to pull uphill. The Nomad is rock solid, does not affect trike handling as long as the load is balanced and you don't overload it, and with a light load you tend to forget that nit's even back there. The aluminum frame is solid and the rest is heavy fabric. The floor is also fabric and I was a bit concerned about holes in it so I cut a piece if 1/4" plywood to cover it inside...problem solved. Included tires are Schwalbe Big Apples and the wheels mount with QR skewers. I've not had a moments concern about the hitch. When not in use it folds to about 6 inches thick. I'd buy another in a heartbeat but I probably won't have to because this won't wear out anytime soon.
