Keep the excursion, we miss our v10 model, even though a lincoln navigator is quieter and smoother. The d [r lock actuators are easy to replace, never had trouble with power windows/switches on our 01, or my super dutys. Shocks, SD or aftermarket springs. And new front axle u joints should cure the handling/ride issues. Excursions are too soft and low, so they bottom out harshly. It sounds c [unterintuitive, but a slightly taller firmer spring/shock combo (a la f250 fx4) will ride and handle better on all but the smoothest roads.
