I think that a 40 below claim is a little much, but honestly, its like a sleeping bag that has a -20 rating, survivable yes, comfortable? I am pretty savvy when it comes to quality, and it is really good, frame/suspension is excellent. Hardware, fasteners were top notch. My negatives were the drawers, the Kimberley are all metal which I personally prefer, and I understand why the tongue is so long, its gives a great turning radius, but they could have had a 16 foot box with the same overall length, that would have been worth it over a little better turning radius. It make the sitting area too small. they did a great job wiring the trailer, this is so important for long term reliability. What ROA needs to quit saying is "Best trailer in the world" What they need to say is its on par with the some of the best trailers made. Its clearly not the best trailer in the world, that is a very bold statement.
