OK everyone, here's what I found after taking rig back to dealer.
The $400 Lippert (Model No. 13504 Multi-Function 5-Output Receiver) controller board was defective with a burned component on it.
To get the slides to work temporarily, the "hot" wire was removed from the power post labeled "External Switch (+)" to the main power leg on the board labeled "BATT." This allowed the ability to get power to the slide switches in the coach to operate the slides. If you have no power to your switches and you have one of these units, check your 30 amp circuit breakers on frame near battery, if good, test both power legs on the board. We found power to the "BATT" terminal and no power to the "External Switch (+)". After looking more closely at the board we could see heat damage to one of the little white square components (no idea what they are called!).
Thanks everyone who tried to help and I hope this can save someone else time in trouble shooting this issue if it happens to you.
I have three photos but don't know how to post here...
