Install Onan in 5th Wheel Questions
I recently acquired an older 6.5NH3CR Onan at an extremely reasonable price which came out of a Class A. I want to install it in my 07 KZ Montego Bay 5th wheel. The 5th WHeel has Gen Prep, consisting of a sealed metal box in the front storage area and the transfer switch. I have an electrician buddy who will do the actual wiring of the unit to the RV. But, I have researched and read multiple articles on installing generators in 5th wheels but still have a few questions and issues to resolve before I tackle the job.
1. I have seen some of the generators mounted on slide drawers and like the idea of being able to slide the generator out to work on if needed; but, if the generator is mounted on a slide then how is the exhaust handled? How would the venting be done?
2. The generator requires venting - will it be necessary to cut a hole in the bay door for a vent cover or can the vent be in the floor of the box - my CLass A had the same generator and there was no venting for it other then the floor.
3. Fuel. The specs say that this unit will burn 1.3 Gal's /hour "at rated load and speed" - if we only use it for mainly running the AC unit or units (I assume it will handle both roof a/c's) and maybe an occassional use of the microwave or coffee pot, what would the average gal/hr be?
4. That leads to fuel. What kind and what size gas tank would be best AND more importantly, where to put it in the 5th wheel - in the same compartment as the generator? In the basement with a gas line running into the generator compartment?
5. Battery - will it need a seperate battery or can i just run the leads to the house battery/batteries?
5. And last, will it be ok to remove the generator from the pan it is currently bolted to and not use the pan at all - with the pan, it would be a bear to try and manuver into the front box?
