Enclosed trailer tongue weight

A few questions about tongue weight on your trailers.

I have a 24' trailer (Gator brand) that has a V-nose frt end. It is not one of the really expensive trailers but it does what is ask of it. The main thing I use it for is to store my Zero turn mowers and generator in it, kinda like a moving shed. I recently hauled my 66 Dart to Ocean City for the weekend. It was the 2nd time Ive used it and a friend had bought a tongue scale so I ask to borrow it. Here are the results that I found.

With the trailer empty the tongue weight of the trailer is 1100 lbs.
Car in trailer and 2' from rear door the tongue weight is 1350 lbs.
If I move the car to center of trailer the tongue weight goes to 1500 lbs.

The trailer weight is listed at 3500 lbs. while the car should be in the 3200 - 3500 lbs max.
That means total load should be around 7000 lbs. I tow with a 2011 5.7 automatic 4 door Ram truck with 6 ft bed. It tows fine and has plenty of power. With load leveling bars the truck squats about 2-3" in the rear and the front comes up slightly. The steering does not get light going down the road.

Ive always been told that tongue weight should be between 8-14% of total trailer/load weight.

I just ordered and received an airbag leveling system for the rear of the truck since Im not going to be able get my tongue weight light enough. So I was just wondering what others have found with your trailers.
