Most light GA aircraft have a trim system that works by using a smaller trim surface to aerodynamically deflect the larger control surface. In such a system, the horizontal stabilizer has a fixed relationship to the fuselage. Later 182s definitely have this system (I owned a 182K for 16 years).

Some light GA aircraft have systems with jackscrews that deflect the horizontal stabilizer as in airliners. These systems are more efficient aerodynamically, but can overpower pilot input, at least in theory. The aero trim system (in prior paragraph) cannot.
