To me it often does not matter. The advice many on here give to match a truck to the trailers GVWR is not always good/correct. Just because a trailer "could" hold a given amount doesn't mean a buyer has any intention of doing it.
A perfect example is my old TT. It had 5000# axles and only weighed 6500# so the GVWR was around 11,000#. The yellow sticker said I could put 4600# of cargo inside. There's no way I'd ever do that so there would be no need to but a truck capable of hauling 11,000#.
In many (most?) instances the GVWR is actually a pretty good guideline but not always. When shopping for trailers I've often just figured 2000# over the dry weight is a good number to plan for. In reality I'm usually about 1500# over dry weight once loaded up with basic stuff to go out with.
