Well, today I went down to the DMV to get the written test for the license endorsement out of the way. Guess what? I don't need it! The lady informed me that the only way that the endorsement is required is if the UNLADEN (empty) weight of the trailer was more than 10K lbs. I said, "but what if my trailer weighs let's say 9,000 lbs and I put 3500 lbs of stuff into it? Doesn't that require me to get the endoresemnt to tow it?" She said, nope. They don't care what trailer weighs with cargo, just the unladen wieght. I said, OK! :huh: I guess I'm good to go then. She said, "yep...don't worry about it! On the other hand if you attach a boat or another trailer to the back of your toyhauler, you'll need the endorsemnt."
It doesn't make much sense since loaded up is actually over 10K lbs, but I guess when it comes down to a ticket or liability- I'm in the clear!
So I guess that answers the mystery to this topic.
