Trailer tongue calculations

Here is a website i found a while ago, and seeing so many building or modifying trailers, it may be handy for the reference.

Very cool, but I don't know how one could use the data to calculate a complicated design like my trailer - where the A frame is boxed and welded aluminum plate and channel, with a bolted in steel receiver and 2 inch square steel extendable coupler mount. None of the possibilities match.... so I guess i will have to see if the tongue drops off one day..... then build it stronger.

I bookmarked the website main page anyway - there are lots of interesting plans.

John, by the calculations on mine, I'm about 4x stronger then needed.
