I usually have to tweak a liberal to get this much knee-jerk reaction. No, I don't think any of you are wrong. Just hard headed and unable to accept that there is a way to replace your deck without cutting and welding no matter how it's built.
Again, it doesn't matter what the gap is. Loosen whatever is holding the boards to the crossmembers, push the board forward as far as you can and just pry it up and out the back. If it is too long for that or there is too much dirt between the end of the board and the head piece, use just a little common sense and cut the board. You are going to replace it anyway. A ten year old can tell you that cutting the board that you are going to replace is smarter than cutting the frame. And easier too.
Then cut the new boards so that you can push the front all the way forward and drop the back into the deck. Center it with an equal amount under both the front and back strap, and attach it. Exactly what seems to be complicated about that?
Or you can cut your frame if you want. I don't care. In fact, you could cut it in the middle and split the trailer like you do your tractor to put a clutch in. That will work as well. But don't embarass yourself by argueing that that is the only way to do it. What ever will make the four of you happy is just fine with me. But you four aren't the only people here and others may actually like to hear that there is a way to do it without cutting and welding the frame.
Don't you guys think it is silly to argure that the only way to get a wood deck out of a steel trailer is to cut the steel when a child can look at the trailer and tell you that if you cut across the deck with a circular saw it will probably fall out and hit you on the foot? I really don't care how your trailer is built If it has a wood deck, the wood can be replaced without cutting and rewelding the frame.

a) We aren't talking about home builts and b) I took this into consideration when I used the term "as 99% of trailers are made" in my second post on this subject. There is no doubt that we will find a few fools out there who are welding in a cap after they put the boards in and before they prime and paint the unit, And maybe the four of you bought a trailer from one of those fools. Who knows?
But the ignorance and bad design of a couple of manufactures and a few home builders is irrevelent to the discussion of replacing the deck. Pry or cut the old boards out. Cut the new boards to slip in. It is really easy and shouldn't create such an uproar.
