Ok, so I filled the fresh tank with water, ensured hot water bypass was off and everything ready to go. My problem is that the fresh water pump would not prime/purge/pressurize the tank. I left it on for at least 20 minutes pumping away and nothing. Is there a by pass valve on the pumps like there is for the water tank? I gave up and just hooked up the city water and flushed all the line that way. The hot water tank filled a flowed fine so I am not sure what to do.

It sounds like a valve is in the wrong position or stuck. Most systems use a manual valve to block the tank outflow to the pump so the pump can be used to suck up the antifreeze. If that valve is closed the pump is not getting water to it's inlet. That is probably what you have. Check the tank outlet, pump inlet and any water control valve panel. Easiest first. ;-)

I would not give it more than two or 3 minutes before I saw water at a faucet.

Ahhhhhh.... Yeah the Viking factory had it winterized as the trailer was delivered to the dealer in Denver in February. I'll play contortionist tomorrow after work then. Thanks!!!

Probably have a valve between tank and pump. Mine has a two-way that allows serves as a tank drain. It also allows the pump to be used to pump in antifreeze when winterizing. There is an antifreeze connector between the valve and the pump. If all valves are OK, look for a low point drain beyond the pump. With water in the tank, and the low-point drain open, it will allow water from the tank to prime the pump. Maybe..

Pull a low point drain or just hook up the hose to city water also if the TT was already winterized it has antifreeze in the lines u want to flush it out before turn off the bypass on hot water heater or Ull fill it with antifreeze and you do not want to heat up antifreeze

With my 2003 Winnebago Journey, near where the hose hooks up to the city water, there is a valve which has a City Water Supply position and a Tank Fill position. The City Water Supply position must be selected rather than the Tank Fill position in order to run the pump. Simple solution but will drive you crazy if you don't know (and might cost you an unneeded new water pump and some RV technician labor).
