9 Gallon WD09450 RIDGID Wet Dry Vac.
Only have two casters on this model, so please see the drop down that shows one option with the wheel base and caster and another with the wheel base only.
Further if you need a different combination feel free to reach out. Also I am able to break down the motor more but thought this would sell as is. Just communicate what you need and I will be happy to work with you.
