What type of battery would you recommend with this generator, and can you confirm if this unit comes with a muffler built in?
Steve 
from New York 
April 29, 2018
Answer
According to the Installation Manual, this unit requires a 12-volt battery housed in a separate compartment than the generator. The specs of the battery needed are in the manual. The unit has a built-in muffler but would still require a tailpipe and exhaust kit to be attached. They will also cover this in the install manual.

Hi Mike. Can you explain the difference between the HDKCD-2209 and the RV QD 12500? Thanks!
Steve 
from New York 
March 15, 2017
Answer
The two gens are very similar.  The main differences are battery charging and warranty. 12HDKCD-2209 is a 12000 watt Commercial Mobile generator with battery charging. 12.5HDKCB-11506 is a 12500 watt RV generator with no battery charging. The RV generator is recommended for use in applications that have living area, sleeping quarters, and restroom and is not being used for business. Standard warranty for CM gen is 2 year/2000 hr. Standard warranty for RV gen is 2 years + 3rd year parts/labor on major power train and gen parts, however, if an RV gen is used in a CM application, it will not receive the full warranty.

Is this OK to install and operate on a bus while it is moving on the road? We have the unit mounted in a school bus and want to ensure it is OK to operate it while the bus is moving on the road. Should we mount the unit on shock absorbing fasteners? What is the specification for vibration from the vehicle to the generator while in transit?
Al W.

Answer
According to Cummins Onan the unit can run while the vehicle is in motion but this will depend on state and local codes. There are many areas where they will not allow this for safety reasons. The unit would not need any additional vibration mounts.
