Loved my Trails West, I had the one with the insulated dressing room with a mid tack and it was awesome as a camper, very comfortable. Heck I even took it camping when I didn't take the mules, I'd load the boat in the back or the atv and have a great camper and gear hauler as well.
I'd recommend a Charmac. I bought a late model and did a little work to it. Tough trailer. Heavy duty. Plenty of pulling my critters on steep, not maintained USFS roads.
