Montana with no electrical

[bix49]

I have a 2002 Montana. It was starting with no issues until it didn't. The van had no electrical activity at all. The battery is good as are all the fuses. I would appreciate any thoughts on where I should look next.
Thanks

How did you determine the battery is good?
Did you load test it or use a voltmeter?

I can understand the van not starting because of the starter, but the other electrical functions should work. shouldn't they? I believe the battery cables are good but I will check them to be sure. Is there a way to know if a relay is bad without having it tested? Could all power to the vans electrical components be taken out by a bad relay and if not what one thing could cause the failure of all of the electrical components in a vehicle?

A new battery can be bad. You haven't load tested it or even used a voltmeter.
To determine a parasitic drain you need an ammeter.
A blown fusible link will kill power to everything.
