Would there be a fuse or something coming from the starter battery?
There is a fuse for the ignition switched functions but not for the starter circuit itself.
Don't make this harder than it IS.
There are two SEPARATE batteries:
One (set) runs the stuff in the coach.
The other one runs the engine and it's systems.
In your case, the one that serves the engine has a problem; either it just simply went dead....maybe because someone left a dome light on....or there is a bad connection at one of the posts.
Many models have an "emergency" switch for exactly this situation. If you hold the switch, it connects the two batteries together hopefully allowing you to start the engine off the coach batteries.
If you do NOT have that switch, carrying a set of jumper cables or a portable jump-start rechargeable battery is a good idea.
