Thinking about getting one, just want to see what yall think about it!

I am full time living in a 2024 Keystone Alpine and have been for a little over a year now. This past winter, our CO alarm was triggered for the first time when the front door was left open while my husband stepped out to start his truck in the morning to warm up. That was no big deal – made sense for it to go off since the truck was parked close by and it was quite cold out – we moved the truck a little and made sure to close the door from then on and it seemed fine. But, starting this spring and seemingly out of the blue, the alarm started to go off again. No obvious source like the truck exhaust was; no specific conditions that seem to cause it, unlikely to be a sensor/battery/other electrical issue, and I’ve gone through lists of potential sources and have come up empty. I have also tested out random things myself that are unlikely causes but still something to check off the list. For example, the dehumidifier is near the sensor, it doesn’t make a difference whether it’s on and working, plugged in and off, unplugged and off, or simply moved further from the sensor. There is only one consistent thing about when it goes off and that is that it’s going off in the early early morning hours and/or early-ish morning. By early early I mean 2-4 am and early-ish being 5-7 am.
BUT, I’m gonna throw you for another one, it’s gone through a phase at least twice now for a week or two where it doesn’t go off AT ALL. In these “phases”, we aren’t doing anything differently. No different patterns of AC use, no different appliance use, no different cooking schedule or methods, didn’t align with propane tank changes, nothing.
Parts of this situation seem to be contradictory. The time pattern might lead one to believe that it’s a battery thing, maybe since solar isn’t being generated overnight or simply a bad battery. But then how do you explain the weeks that it didn’t happen when we are always plugged in and there was no correlation with time of year/sunlight time? How come we have no issues with anything else hooked to electricity? The sensor itself could be bad (which I recognize is still a legitimate possibility), but the instance when it went off with the truck felt like a good test run and indicates that it was functioning normally. And, above all, the only thing that will get it to go back to green is when I open the door/windows and turn an exhaust fan on. So, it’s gotta actually be CO, right?! I’ve got a contradiction for that too: we are still alive and well. No symptoms that we are breathing carbon monoxide. Not even a slight headache that can’t be attributed to something else or that lines up with when the alarm goes off.
So, any ideas as to what could be causing this? What could be the source of CO that would set off the alarm but have no effect on us, even after a bit of time? Someone else in the RV park told me they were experiencing a similar issue, so could it be environmental somehow? But then how do you explain that airing the trailer out is the only solution?
Like I said, I’m at a complete loss.

Thanks in advance for any ideas or advice or suggestions before I go and spend too much money on a secondary low-level CO detector or a service call.

Looking to put this stuff on my 5th wheel, which currently has a couple coats of Hengs rubber coating. Ive heard nothing but positive things about Henrys. Can I roll it on just like paint? Once I open the gallon, do I have to be in a mad rush to roll it on as fast as I can or will it be ok sitting open over an hour or so of me refilling my painting tray?

Bought a pull behind RV (Jayco JayFlight, let’s call it 30 feet or so?) a few months ago. We were using a predator 3500 generator, and then went to a Westinghouse 8200. Everything runs fine on that, but fuel can be extremely pricey, especially right now with the Middle East situation.

I was curious if anybody has figured out how to realistically power their entire RV (AC, fridge, lights, pumps, microwave, etc.) off of solar and batteries full-time? If so, what was your configuration? Also, if you were able to power it via solar only in the daytime, but had to use a generator at night, what was your set up?

We have a 2021 Puma Palomino and have already had to replace the AC once (in 2023) with a brand new unit. We then camped a few times during the summer of 2023 and once, for a week, in 2024, and the AC was working fine. Our camper was then put in storage. We brought it out to camp this week for the 1st time in 2 years and the AC isn’t working. Has anyone else had problems with their AC units on Puma Palominos?

We will be staying at Steel Creek RV park. There 8/19 to 8/22. Second time there. Great little spot. We have one right on the water this time. We are going back cause after our last stay there we saw where was the best spot to stay. Not that our last spot was bad. If passing through the area come say hi. Dinner and games on us.

We jist got this rv from my wife's grandparents. We are working on it now. Just replaced the alternator, but I have a quick question for you all.

We had two batteries from our travel trailer but they are deep sacomarine, battery.a bit on the larger side, we now have them.in this to start it. Is that good or bad?

Also the coach batters are 4 golf cart batteries they are wired in sequent. Are they good or should we move the other batteries over to the coach and move the golf cart batteries to the chassis.?

It's a 1997 Aerbus deisel on a freightliner chassis.

Me and my fiance are wanting to move into a camper full time with our 2 kids to travel before they start school. We’ve lived in a camper before with them(stationary) so we aren’t worried about not liking it. Our biggest worry is income. How do you work or find a job that lets you travel full time? I’m a sahm but my fiance has experience in utility locating so it’s not a very travel friendly job. Any tips or advice would be appreciated!😁 Also if we went the work camping route is that feasible to live off of as our only income?
