Another factor to consider:
TTs weights can vary a LOT in the course of a trip. fresh water gets used and ends up in the grey /black. Food gets eaten and leaves the cupboards/fridge , and ends up in the waste tanks. Clean clothes get worn and end up in the dirty clothes. Propane gets burned and disappears. Etc. Many other things may shift around as well. How big a factor all of this weight moving around is for you.....Is impossible to predict. It all depends on YOUR usage patterns and the layout of the trailer.
Nobody any forum can tell you either.
Using my TT as an example... I have FOUR 42 gallon waste tanks! That is 1344# of waste! We usually tow it home with full waste tanks. So our weight distribution, just in tanks is far different than it was at the beginning of the trip...
Keep that in mind when selecting your TT/TV.
Cutting it close on weights can leave you with a bad match. You need some leeway, as until you actually use it.... It is all an estimation.
Better to error on the good side of the limits than on the bad side... And it is a lot cheaper as well.
