Trent is a Free Spirit. He's never afraid to go out into the world and get what he wants. He is a dedicated father, and loves spending time with little Tina.
Trent wears jewelry which is uncommon for pre-made Sims. While the jewelry he wears can be accessed in normal Create a Sim, but can't be accessed in gameplay, Trent's household has access to jewelry that can't be accessed in Create a Sim, even with debugging mode enabled. This can be proven by changing a member of the household's appearance. There is a mod which unlocks the vacation jewelry so that it can be accessed in normal Create a Sim.
Even though Trent has light blue eyes, his SimDNA in SimPE reveals that his genetics are for grey eyes. He and the other members of his family are some of the only Sims in The Sims 2 whose eye colors do not match their genetics. While it is very simple to change his genetics to match his eye color, it is much less simple to change his eye color to match his genetics, since it requires opening his character file, and changing multiple genetic codes.
Trent's face is a slightly modified version of a pre-made face from Create a Sim. The face is in the bin for adult males with light skin (skin tone 1), and has a blond mop top and glasses. This CAS face, if used on toddlers or children, has a shrunken chin and plump face.
Chester Gieke, Jason Greenman, and Gabe O'Mackey also use slightly modified versions of this CAS face. There are other versions of this face which can be found in the bins for child, teenage, and elder males with light skin, and young adult males with tanned skin. Blair Buckingham uses the elder version of this face with no further customizations.
