Usually motorhomes are set up so that if you're low on gas, maybe less than a quarter tank or so, the generator won't run. (This is done by having the generator gas pickup tube stop somewhere above the bottom of the gas tank). That way, you can't run out of gas and strand yourself by running the generator.
It should still crank even if it's not getting gas. (If you mean it cranks but doesn't fire, that's still turning over; the motorhead terminology can be a bit confusing if you're not used to it. Turning over just means the engine crankshaft rotates somehow.) Slow or no cranking would suggest that the house battery is discharged or there's a poor connection somewhere between it and the generator (usually it's connected to the house battery and not the chassis battery). This could be either a positive connection or a ground connection. There are other possible causes, but those would be the first ones to check.
