Q: Can I still use the FastGun WobbleStoppers if I have a dual-rear wheel truck?

A: Yes, of course! You can use either the (A7006) for round jacks or (A7016) for the square jacks. Most likely, you will have a dually kick-out bracket for the jacks. You will want to install the mounting brackets so that you have clearance between the jack leg and the dually fender when loading and unloading the camper.
