Well, technically I have started... sort of... the trailer is out of the box

so that counts for something right?
Its funny, the profile doesn't actually bother me much, although to be honest that might be because it is several steps down the road. When I get to that I will undoubtedly stress over it too.
I will have to give some thought to not moving the axles, from all my reading, that seemed to be a basic "given". I think I still will, because my trailer is 4x8 and I want the tear to be 5 x 9 or 10. But it definitely deserves consideration.
I suppose I am being overly cautious, but I don't want to do something stupid or irrevocable. the thought of modifying plans, even greatly modifying, doesn't bother me at all, as well as incorporating my own ideas, you all might kick me off the forum if I didn't show SOME originality.

The scary part for me is that I might ignore something that is taken for granted by most people, ie the spacing for a galley hinge, or something. The what doesn't really matter except that I might not know it, and have a leaky, or unsafe, or inconvenient, etc, trailer because of it. That is why I want some plans, more to have a direction to travel in rather than a destination. if that makes sense.
On a side note, the only downsides to this forum (few) is that there are so many ideas, none wrong but many mutually exclusive of each other. I look at someone's trailer and think "that is awesome", then I see another one and it is awesome too, but if I do that I can't do the first thing I saw! The other problem is that I see so many amazing builds that I know mine won't be as good. (doesn't mean I won't try to make mine the best, just need to get past my roadblocks):D
ok, I am off to peruse those generic benroy plans again
