It's not a short, a short would be blowing fuses. And, as I type this, maybe it is a short and the fuse is blown. Check the rear lights fuses.
Usually, this problem is an open somewhere (a smaller than normal load causes the flasher to flash faster). Usually, the open is a burnt out light. Please note, each lamp has two filaments and two functions. One filament is for the tail lights and the other filament is for a different purpose. On one lamp, it is the brake light, on an other it will be the reverse light, on an other, it will be the signal light. Note, on some trucks the stop light and the signal light will be shared.
If the bulbs (lamps) are good, the problem may be a broken wire, or a poor connection somewhere. Check inside the bulb socket for corrosion, check the plug where the wires connect to the lamp circuit board for corrosion, etc.

thanks rayvoy. I did check the plug where the wires come from the tail light and go under the truck, there is I guess you call a harness?, its like where there are several plugs mounted under the bed of the truck. anyways, the plug that comes from the tail light was loose, not connected all the way. I simply pushed it on snug and WHAMMO!! everything works fine now.
