Just to clarify, running your truck in 4-wheel drive on any surface that doesn't allow for some slippage of the tires will cause damage eventually, whether you drive in a straight line or not. 4-wheel effectively locks the front and rear drivelines together, and any minor difference in tire wear, etc. will allow torque to build up in the drivetrain (unless tires can slip to relieve the stress). This is why in the old days you sometimes had to drive in reverse for a short distance to be able to shift your transfer case back to 2-wheel drive... you had to effectively unload it.
Personally, I'd never advise using 4-wheel on any paved or otherwise smooth surface, wet or dry.
