What Onan Gen set is my 2019 Nitro 28KW prepped for?

[Captain Jim]

Does anyone else not get replies back from FR? Gave them my VIN and asked what model ONAN. Sent them a message and no response?

I am trying to figure out which model Onan I need. I know it will require the 5.5K as it is a 50 Amp Service. There are about 5 or 6 models available, EVAP and non-EVAP, need to know which one, so I can shop around.

Also, read in a forum here that it must be a carb model, not EFI? This I am surprised by?

Does anyone have a 2018/19 Nitro with a Onan?

Thanks!

Kiss, that's why a carb and not fi. Also the expense. Much easier to work on an old style fuel system.

You will need the EVAP unit to comply with the EPA regulations unless you go with Propane. If you go with a gas unit then you will also need a fuel tank which is expensive. Plan on about 6K for the generator and $1k for the fuel tank including labor and taxes. You can go with Propane and then you will not need the fuel tank but I found that they don't get as good fuel economy as gas and the tanks are heavy, about 50lbs.

Thanks for the replies guys!

Rocco, my Nitro has a 30 gallon fuel station tank and the evap canister already from the factory. It has the gen prep package with the controls on the panel inside the trailer, the fuel line and return line, and all the wiring to hook to the gen set already in the generator compartment. I am just trying to figure out from FR or someone with experience, which Onan I need to find?

You are a lucky man Captain. I had to pay for all of that stuff including a generator shroud. I have attached a spec sheet showing the different models. You will need the 5.5 HGJAB-6755* (7866**). It checks all of the boxes. Please read the owners manual very closely. The cutouts underneath the unit are critical.

Thanks for your support Rocco, much appreciated!
Yes, I made sure I bought a rig set up for it. The manufacturers are not putting the gen sets in anything anymore, as most don't want to pay for them, and are usually hooked up at a campsite.

I am into hauling German Shorthaired Pointers around the country, and expect I will only get more involved once I retire. Want to be able to take dogs from my truck into the trailer when we stop somewhere, and keep em cool, after stopping short of where we want to stop to start the AC ahead of time! Also nice if it is hot and we want to stop and take a break for lunch, pre-cool the rig the last 1/2 hour of driving! I do have a plan in mind!
Have kids in Phoenix, Tampa, and Charleston as well, so pretty sure we will be running some AC!

I assume you have the Onan, and curious how you like it, how you use it, any pros and cons you can share always appreciated.

Thanks again Rocco!

Yes, I have that same unit. It works great. It will run both my AC units and Battery Charger/Inverter at the same time and at 6000 feet. It was installed in May and it has over 40 hours on it. Still running with the original tank of Ethanol Free gas (very important). There is also an adjustment knob for Altitude that you should pay attention too. One thing I found is that the Generator runs cooler with the door open even though it is vented. I could not find Onan oil and filter for it around here so I ordered a full oil change tuneup kit on Amazon.

I meant the door to the compartment not the one on the Generator itself. That one must be closed at all times while running.

Well, a bit disappointed with FR yet again! Looks like CW was right, no way the Onan 5.5KW unit will fit in my compartment? Yet the trailer is set up with 50Amp power?

So I buy a trailer with Gen Prep, they say it is all set up for the gen set, and tell me 5.5KW when I call them, and now I need to find out if all the wiring will hook up to a 4KW unit?

WTF?

[Captain Jim]

Ok, here are a few pictures of my Gen Set compartment. The fuel line and evap line are a no brainer. There are two black cables, ground from battery and assume the other is chassis ground, as well as a red pos. from battery.

Then there is the black plug with 5 pins/wires I assume is the remote controls from inside? Then, there are the 2 ea. white, brown, blue and greens that are in the plastic connectors.

Based on other posts on this subject, I should already be wire with transfer switch and everything?

I am also assuming these provided wires should hook up to the 4KW Onan, since the 5.5K will not even fit in the gen compartment? Even though the shore power on my 2019 Nitro 28KW is 50 amp?

Anyone have any experience with these wires, and the 4KW Onan?

Thanks in advance for and help on this subject!
