Does your generator start from deep cycle house batteries OR dual purpose house batteries?

To my knowledge most all coaches wire the genny start to the house batteries.
Exception would be some really cool rigs like Bluebird wanderlodges, their gennies actually have their own battery!
Not true at all. There is NO real reason. ALL OEM's make their own decision on which battery bank to use. The "general" rule is, a Rear Engine diesel with the APU up front will use the Chassis batteries to start the APU. The do that because they already have to run a heavy large battery cable up front from the chassis batteries(most are in the rear) and they do not want to run a extra dedicated battery cable just to start the APU. Also, GAS motorhomes usually do have the Coach batteries start the APU since the coach batteries are closer to the APU than the chassis battery that is up front. Doug
