Yes, I've a 5x9 off road version from
TC teardrops (they are based out of Wisconsin, small family type operation)
It works well for me and 2 dogs, so far I've spent around 35-40 nights it in 2+ years I've owned it. Initially I had a regular 5x9 that I took for a week long trip in wyoming, and quickly realized I could well with beefier frame and bigger tires, and went for off road version, especially for trails in southern utah. In winter I use one of those little buddy propane heaters, run it for few mins to get inside nice and toasty and turn it off. Here's few pros/cons in regards to teardrops I've seen after 2 years of ownership.
Pros:
1. Easy to tow(mine's around 1100 lbs)
2. Small profile means I can go to remote places bigger trailers can't go. (Not as versatile as sth like turtleback/patriot trailers, those things excel at off road gnarly trails, but they dont have hard sided sleeping quarter).
Cons:
1. It's just a sleeping room with kitchen/galley area. Cant stand inside it, not much room. but if all you care about is nice place to sleep at night and being sheltered from elements, it's great for that.
2. backing a trailer is pita, and i've found myself couple times where Ive had to unhook it out on the trail coz it was too narrow or sth. So now whenever I venture into some new area, always mindful of how wide the trail is, how well its travelled and such.
3. This is mainly because I go out in off road trails, but stuff in galley area just gets trashed after a good ride. Need to find good way to secure food items and others properly, or dampen the ride somehow. So now I only store firewood and random stuff on the back, stove/cooler stays in my car for now.
Anyway feel free to ask any questions.
Here's couple pics of my setup.
