I know this is not your question but once you get it going then you have to worry about where you will be able to use it at the public camp grounds and places.
Here on the East side of the US I am always running into places using my Honda 2KW portable generator that have generator use restrictions which varies from place to place but most often it is a couple of hours in the morning and a couple of hours in the early evening. Not many places have it allowed during the whole day and very seldom see it available after 8PM at night... Some of the Natl Forest areas now have it allowed in certain spots from 8AM to 8PM but never after that. Being built-in you might get away with running more hours.
Thank goodness for me I can live without air conditioning and high wattage microwave operations that allows me to get by just fine using my additional batteries and beefed up wiring on the trailer and changed over lightning to LED units...
We can do almost everything we at public electric hookup sites with the exception of the Air Conditioner and the High wattage microwave unit.
I am all planned out to run the one day/night off my batteries then at 8AM the next morning during breakfast I can run my 2KW generator to connect to my trailer and recharge my battery bank back up from its 50% charge state to its 90% charge state in a three hour generator run time. Then i am good again for the next day/night run off my generator...
This is what we have been doing since 2008 with the off-road POPUP trailer camper camping off grid out of Virginia up and down the Blue Ridge parkway and the East and South East coastal areas mostly at public camp places. TN smoky mtns and the high country areas in the VA-TN-NC-GA-AL are my favorite places to go...
I am thinking about adding a few solar panels to reduce some of the time my generator has to run to keep my batteries up when in high sun.
I would imagine those Troy Built generators are very loud to use in the public areas. Folks frown at me using the Honda Inverter type generators sometimes...
