I'm not sure why the GVWR is so important, other that knowing how much you can pack into the trailer. For instance take to trailers that both have the empty or dry weight, but one can handle 2200 lbs or cargo and the other 1200 lbs doesn't necessarily mean you are going to pack more stuff. So I would think its better to look at the dry weight that is written on the door as a startling point. Oh course I agree that once you've packed the trailer that it should be weighed and checked against the trailers GVWR making sure your within limits....no??
My tow vehicle is 2006 Toyota Tundra and not an SUV. sorry I should have mentioned that.
I agree that the ultimate tongue wt should be based on what the trailer weighs plus what is packed into it and it should be actually weighed. I was just trying to back into an acceptable dry trailer weight, since that is how most are listed. You see I'm finding it impossible to find a used TT that my truck can safely pull....that the wife likes.
My goal was to find a used trailer that my truck can tow, so we can try-out RVing without dropping too much cash. Well that doesn't look possible now.
I wish I had an extra $50,000 so I could buy a new truck.
