My trailer is getting new boards. I didn’t like the cracks I was starting to see. I’m trying to get it ready in case I need to get them out of here in a hurry. I’m still looking for a “living quarters” but this works for now. I need to get a couple of new tires too.
Are you going to use pressure-treated boards? That’s what I’ve got in mine (2x8s I think). They were in there when I bought the trailer nearly 20 years ago and they look as good now as they did then. I did have a couple of extra angle iron supports welded under the floor when I got it though, so you might want to consider doing that while you’ve got the floor out. My FIL did mine, but I wouldn’t think that it would cost that much more to have them added by somebody else. I had them put right under where the horse’s feet would go because I’ve always had a horror of having a foot go through the floor.
