Repost for the evening Mathematicians. Trailer Loading Question and the Morgan

What direction to park the Morgan in, and how to calculate CG?

I’ll take any ideas before I hit the open road. My question is simple.

Does a correct tongue weight, 10-15% of the total load, mean I am within the 60% in the front / 40% in the rear weight loading rule . Therefore my CG is correct. (Can this assumption even be made)

Morgan weighs 1300lbs, and has a 61% front / 39% rear weight bias.

Trailer weighs 1200lbs with an empty tongue weight of 125lbs

Total weight= 2500lbs total.

Loaded engine first the tongue weight goes from 125 to 500lbs, 20% total load. When backed in tongue weight is 300, 12% of total load, and within the correct range. All weights were taking with a tongue scale.

A few unknowns is where the center point of the Morgan is, and the CG of the empty trailer. Some pictures for reference.
