Wont start

[Debra]

Our 2007 Thor Outlaw will not crank, no lights come on but radio is working. What do we need to check.

The chassis battery is probably dead. The radio operates from the house batteries. Did you try your "Emergency Start" switch?

Hold Down the emergency start switch for a 10 count. While still holding it down, try starting the engine.
If that doesn't work call your roadside service provider or ask whoever is parked next to you for guidance.
