Three different cab styles are offered for the Titan and Titan XD: a two-door regular cab, four-door King (extended) Cab, and four-door crew cab. The four-door crew cab models were the first trucks to debut, followed by the King Cab and regular cab. Trim levels for the Titan and Titan XD are S, SV, Pro-4X (4X4 only), SL, and Platinum Reserve. The regular cab was only available with either S or SV trim levels, while the King Cab was only available with S, SV, or PRO-4X. The crew cab was available with all trim levels.
