Hi Perm:
Thanks much!
That's exactly the info I was looking for, even though it'll cost me a bit more money. I certainly do not want to make "improvements" that decrease the value or integrity. Rather, if standard "cargo" accessories (e.g., E-track or Airliner track) are wisely placed, the trailer can be quite versatile without locking in any particular configuration, not to mention "unnecessary complications". (In fact, maybe there could be a whole discussion tips and ideas exclusively for "versatility".)
Thanks again.
Phil
