Gen 3 Vibration

[toyota hilux]

Hi Guys

ive just been away to scotland for 4 days, the truck performed perfect as always, however i have notice that when she is idling there seems to be a vibrating coming from the back of the car.. The whole exhaust system is rusted and needs replacing, could it just be that i need a new exhaust, or could it just be something loose or something more serious?
Btw the vibrations goes at about 15 mph :S
Thanks

when you say idling, when stationary or when rolling at tickover? Could be exhaust, spare tyre holder or something in boot, especially if you're not moving.

Put your foot on the end of the exhaust and see if it stops.
