thanks for the input on the trailer guys! I think your all correct so Im building a 23footer.
Not sure if dump trailers are built exactly like this, but I this is how im building mine so if its not scale we will just call it a custom
i know it looks a little sloppy but I was in a hurry to go out so..
as soon as my 5th wheel and kingpin arrive from joe I will be able to sit the height of the axle mounts..So I will just keep working on the ther rail and the crossmembers till it shows up..
