Poor man's build-in generator for long box AF865/811(?)

I mean, is that so difficult to understand? There is this lizard brain feel to have things inside.

You're a new member so I'll tell you that you have (accidentally or on purpose) stepped in one of the RV.NET piles of dog poo. Many battles have been fought over generators. Take my advise - let it go. PM me if you want the whole thread gone.

Believe me, you won't convince anyone here.

Ok.I guess here is the real question. After modifying the compartment so the genset will fit in there why not just pull it out start it and plug it in. As you said in your post “its just for back up in case the solar dont work out”.

I look at your pictures and all I ask myself is why? You still need to go out and start it, you still need to pull it out to fuel it, you still need to pull it out to service it, you still need to get out open the door and run an additional fan in front of the door.
What is the gain here?

The benefits of a built in genset are.
Uses same fuel as the coach (propane for a camper). No need to carry additional gas
You start it remotely inside
It’s tied to a transfer switch so you can back feed the outside shore power connection

Your installation has none of these benefits. Yes there are some big negatives to an onboard genset that campers use but none of those are safety negatives. They are approved,vented,and exhausted to prevent any potentials for loss of life.

Just some food for thought.

The factory install one...got a vent on the door. that is not very hard to DIY. you made it sound like they contact NASA for enginnering advice to maximize pilot survival. It just a dumb generator. It snuff itself out when there is no air. 85% of cause of death relating to generator is carbon monoxide poisoning. It is at the safest place possible.

And I can make it better. I make it vent downward to a chute. Just because people charge you 1000% markup for something doesn't mean they know exactly what they are doing.

Well, there’s one big benefit, he’s got somewhere to put the thing!
I suppose at $150 one of those sets can be considered a throwaway.

I’ve seen portable generators in truck campers that were on a slide-out tray. That seems the slickest way to do it. It would require a little camper surgery on yours to install a taller access hatch, if that’s feasible. I’d still be a little leery of using it that close to the camper if I had the A/C on and windows shut. Maybe if I had the windows open and some breeze, otherwise I like it just a little further away. I might be overthinking it but I don’t wanna wake up dead.

You bet Kayteg1. That too!!!

You forgot the safety-design exhaust that will not kill you. (you still should observe wind direction)

I think you are confusing inflation adjustment with value holding.
I can only compare it to my John Deere tractor/backhoe.
Bought it in Nebraska for $8k. Used semi-commercially and for my new house excavation for 8 years only to sell in California for $12k.
I consider $150 generator as a very good option when I don't need AC and extreme convenience of having small size that I can take anywhere, anytime.
Sure it takes 3 pulls to start, when my 12 years old Honda starts on 1st 90% of the time, but I bought my new Honda EU3000 new for $900. How much are they today?

Those things are pretty well known to be junk... I have one solid argument why Hondas are actually a bargain. I sold my 12-year-old well-worn pair of EU2000s - that still worked perfectly - for $700 each. Then bought myself a nice new pair for $900 each. (I believe they’ve gone up $100 each recently).
Twelve years later I got most of my money back for the Hondas. They really only cost me about $18 dollars a year each!!
Why would you run louder (forget the claimed specs, check out some real world tests), less reliable, good-luck-getting-parts junk when the good stuff is actually the better bargain?
The cheapo sets usually claim similar or slightly superior power output specs but they are being optimistic while the Hondas are conservative. The Hondas always outperform in real tests.

I’m just postung this because it’s one of the bigger “penny-wise, dollar-foolish” things truck campers are involved with. I don’t throw money at my camper. I just don’t like to throw my money away.

I think it is reasonable to look at how factory generators are installed including what the floors look like and how they are vented. They also have remote fueling will hoses instead of tanks in the compartment. Gasoline vapors sink, for example.

There’s no “dirty” 12V power, it’s DC. It’s not ideal for charging only because it isn’t regulated to lower its voltage when it senses less load, like a “smart” charger does.

This generator install definitely needs an exhaust system. Sure it’s a generator compartment but the sets its designed for aren’t portables. Even if fumes aren’t an issue, heat will be.
With a fan and an exhaust I think it could work out fine.
Exhaust is tricky if you have to be able to easily remove the set to fuel it though.
