http://Challengerdoor.com The series 805. Based on a label I saw at a recent TJ gathering, they make doors for a very large teardrop manufacturer.
It's a little rough, I had to go outside yesterday in between rainstorms and laying tile in the bathroom. BUT. This video should give a pretty good idea of what they look like.

A few notes:
1. They are screw in from the outside, straight into the frame, with some sealant / putty tape underneath.
2. They have slide up hehr windows. They have screens in them and are either up or down. My others have 2 different levels of "up".
3. The have an inside trim ring that looks like it is made so that you drill your own holes and mount it from the inside with screws.
4. On the outside there is a separate drip edge trim piece that mounts to the top.
5. These are 26x32 (actual 25.5 x 31.5) with a 4.50 radius (4.75 cutout) on each of the doors. I wouldn't think that the 36 inch doors would be that much more... but I know that part of it is a bit apples and oranges as far as price.
The total cost of each door was $205. The packing and shipping was $70 total to GA. $480 Total




I'm not saying these are any better or any worse than those that are sold by other TD trailer manufacturers, but they do seem a bit cheaper. My initial impressions of them are good, as good or better than my other doors that cost a good bit more. Again, not "knocking" any of the other folks that sell them, just posting what I have found for others to refer to.
