From the pictures it looks to be worth the money of course I'd try to chisel them down a couple grand.My worry would be the dressing room is awefully small the entrance door is the beginning width so that mean's around 7 ft. on the long wall with a shower and stool not much room for a table or anything else also no fridge. I'd check with Twin City Featherlite my mom and sister both bought fancy horse trailers there and they have more creature comforts. My Mom got a 3 horse a few years old for 19,000 but it has a stove, fridge, shower, generator, looks like new.
Back to the dressing room size I built a few small one's like that and the owner's after thought was they were awfully small that and the roof bows are exposed so that looks like all they did was carpet the roof between the bows that would get awfully hot and loud if it were raining. I guess It would depend on what you are using it for and how your camping skill are. Without a fridge your using ice and coolers so it's a toss up.
