My guess is something driveshaft related, either the slip yoke at the transmission connection, or on many long wheelbase trucks there is a constant-velocity joint in the center, or a carrier bearing there, that may have some play.
I have experienced that on my 2500 GMC pick-up when towing my trailer. I removed the driveshaft and lubed the splines and it's been good for many miles. I had a clunk sound when moving from a stop.
The OP hasn't said much regarding his experience with all things mechanical so hopefully something said here helps.
If the splines aren't lubed on the driveshaft, they can bind and then suddenly release at a stop when there is no torque on them. That could feel like a little bump from the rear.
