Thanks for all the input!
As for your questions Ira and Steve, the lip on the door is 6", which is a little high, but I can get in and out of it easy enough. I think the problem with the door happened because I believe the plans we used call for having the walls sit against the side of the trailer, and we decided to rest them on top, and had already cut out the door at that point. I still think it'll work fine, but your right, it could be a little annoying.
As far as the door/wheel locations, I read your post and then looked at the picture, and it does look like the door won't clear the wheel, and I'll admit, I was a little worried.
So I ran out and threw the door up and checked it out, it opens just fine. I think it's just a weird camera angle.
Steve, as far as the axle goes, it's also just an odd angle; the axle is in its original position.
Thanks again for the observations!
