I have a 2007 Sundance by heartland. Had it a few months. Nearing Reno completion. The furnace won’t even start the fan. Battery is in good shape. All the fuses are good and the power to the a/c is on. Where do I start?

Check the igniter. If you're lucky, you may have a view of where you can see it spark.
 
The first thing in the furnace start sequence is the fan should run. If that is not happening then there is no power to the unit or the Tstat heat demand wires is/are not connected.
