Saw this same problem (which by the way is common) on anoter forum
Suggested the following
Battery Disconnect (Salesman switch)
Disconnect solenoid (the device that actually does the switching)
BAD CONNECTIONS (The winner in that case)
Bad cable (had that found it before it was a proglem, repalced it)
Blown main fuse or circuit breaker (Battery)
But first, Make sure the batteries are fully charged.
Rather than a volt meter,, which means you have 3 things to hold and look at, I like a test light, This is a device that looks like an old fashion ice pick (and in fact may be used as such) but witha clear or translucent handle and a wire coming out the handle.
The wire has a clip (Alligator clip usually) on one end and there is a light bulb inside the handle
You start by touching the clip to one battery post and the tip of the pick to the other BRIGHT LIGHT = Good.
now with the RV not plugged in move the clip to a non-painted frame part LIGHT GOOD Dark bad ground cable
Move out along the positive wire, When you come to a device check both BIG posts (if it has both big and small) .. When you need to move the clip, touch the last tested good point to insure you still have a good ground.
Continue till you find DARK, problem exists between LIGHT and Dark.
