Does quiet time in your campgrounds mean no vehicles are allowed to run? I have never heard of that. The stock PB is pretty quiet. Don't think anyone would be complaining about it running.
I was planning out a rebuild of my trailer's electrical system to add some LifePO4 batteries, inverter, the whole 9 yards.
But then I got the new truck and that's where my money will be tied up, so I'll put that battery upgrade on the back burner. But in a way, having the new truck also helps out in other ways so it's definitely a net win.
I'm really looking forwards to getting the new truck delivered, still about 2 weeks out. It's a big upgrade to my current '99 F350 and a '04 Tundra. The built in generator on the F150 was one of my "must have" items.
I already ordered the L14-30 to TT30 adapter so I can hook my trailer up directly. It's amazing that I can do that and still have another 30A on the other half of that split phase for something else. I'll charge my inlaws a nominal fee so they can recharge their devices.
Depends on the RV/camp grounds but compared to a normal gas generator, the PB is on par with Honda’s "Super Quiet generators" which only produce around 48-50db under load. Plus since it's acting as a generator most places probably won't say anything about it.
It depends... and that's a good question. How loud is too loud?
It's a National Forest site and there's a mix of RV and tent campers, and it's those tent campers that I try to be aware of (especially since my inlaws are part of that group) 
Maybe I misunderstand how it works.
The double honk is easily fixable. Options are to leave the spare key fob in the truck when in generator mode and HVAC on speed 5 but at a warmer temp such as 75f to keep the interior from getting too hot and then locking it with the other fob. This will prevent the dreaded double honk but keep the 12v system output at 14.0v or higher and prevent the 12v batteries from being slowly depleted over time. You can also use Forscan to disable the double honk "feature" we all now and loathe all together and not have to worry with leaving a second fob in the truck.
This is another option. This will let you turn that feature on and off easily and anywhere. Not cheap but it does offer a lot of functionality if you are looking for this option.
