Older well built or newer TT

I had a couple of reasons for buying used---1)I wanted more insulation, better mechanicals, and a floor plan I liked. 2)I knew I wouldn't have the heart to tear apart a new trailer to accomplish #1. In retrospect, it was a very good decision as I accomplished #1,was able to hold initial cost to a minimum, and the result is a good towing trailer that should last me a long time. Total gut and restoration isn't for most folks but some of the vintage trailers were built when materials didn't need to be skimped on. That results in a better product, IMO.
