How often do you all repack the wheel bearings on your TT's. Should it be done every year or a specified mileage/usage. Thanks for your advice!

Local hitch/trailer parts dealer said it is possible! Reason being is most will add grease before a trip, with "cold" grease/bearings. If the old grease has hardened up some the new grease will take the path of least resistance, usually past the seal.
From my understanding, you will not blow the seal if you are slowly hand pumping the mechanical grease gun. For obvious reasons I would not recommend using an air or electric powered grease gun. Here’s one caveat: If your rear seal is already in poor condition, then you might have a problem. Sometimes you or a technician might inspect the brakes and fail to put on a new seal when pulling the hub. It’s also possible that you or a technician might damage the surface of the seal on the spindle threads when sliding the hub back on. Older dry seals may fail to reseat. These things can make the seal weak and result in a leak when hand pumping. This is not the fault of the EZ lube.
The purpose for the EZ lube is to keep fresh grease in the system. It is designed to flush out dirt and old (dried) grease. Upon flushing your bearings, you have extended the life of your bearings and have allowed them to run cooler. I can vouch for this by the thermal data that I have collected.
