By "top" do you mean topper, canopy, shell etc to mount on the bed? If so, almost any fiberglass shell is available with heavy duty reinforcement (commercial or sportsman's configuration) that can have tracks attached to mount crossbars, suitable for mounting an RTT. Many many threads on here on this topic. If you mean a tonneau cover (flush with the top of the bed) there are also rack options. tacomaworld.com also has much information and many examples, some specific to the current (3rd gen) Tacoma.Does anyone know of any fiberglass tops for the latest generation Tacoma that either has a roof rack, or designed to have one installed that would support a roof top tent?
Or what would be another option to have a top on back and a RTT?
Thanks!
