Yet another pin weight calculator - need testers

I have been working on a web page for calculating pin weight percentages based on dry weights + then estimated an actual loaded weight for folks who want to get an idea of what their pin weight might be on a specific camper. It's largely geared towards fifth wheels as that's what I'm most familiar with, but I think it should work with TTs.

Anyway, if you're willing to test this out and are relatively "in the know" on weights and calculations, please PM me.
