Just a Really Really Stupid Question
A gentleman I spoke with is incorrect, I ask the question here to confirm if you and or can not.
I said that I wish I had a connection on my Class A that I could use to connect a smaller external propane tank and refill the onboard or use it as a standalone. He said the connection for the grill can be used to add propane to the tank. Is he correct?
If so it would handy when you off the main roads boondocking.

I use an " Extend-a-Stay " adaptor to hook a BBQ 5 gal bottle to the coach system .
I imagine I could , open both the bottle and the coach tank valves and have some propane go into the coach tank , but very little would flow and once both tank and bottle pressures equalize the transfer would stop.
That's why fill stations use a pump system to fill the tanks .

Generally no, you can't transfer liquid propane through the vapor connection. Maybe if you turn the external tank upside down you could get some transfer until the pressures equalize as Skip said. But connecting an external tank through the Extend-A-Stay lets you run the coach appliances off of the external tank.

Thanks! I just wantvto verify it. The main reason I ask is we’re considering a Class C with a 14-gallon propane tank and a propane generator that can uses half a gallon per hour. It would be great if we could have an extra 5 or 10 pounds of propane.

While you can't readily fill the on-board propane tank you can set it up so that a remote tank can fuel the generator. I would avoid an RV with Propane generator if had plans to regularly use it. Onan does offer a small Deisel generator. $$$ With a propane generator I would look at increasing battery and inverter capacity, using solar, and have a system that can recharge the batteries quickly off the generator to reduce needed run time.

They do have a Generator Delete option and a 960-amp battery instead of the generator. This is a Class C with limited payload, and I am trying to find out the difference in weight between the generator and battery. Standard it comes with a 300-amp lithium battery and 200 watts of solar, and the 960-amp option comes with 400 watts of solar, which is nearly enough to keep the 960 amp battery charged.

To be more helpful what model coach chassis are you looking at? Is it Sprinter based?
Some of these will also offer an option of an additional alternator, sometimes called an under-hood generator. Part of the decision process is knowing how you plan to use it. If driving every few days the UHG can top off the battery bank and solar can provide some fill in. I see many that use battery-inverter for all including stove top and water heater along with AC. There are options.

I’m not gonna lie, we’re getting older faster than I’d like to admit. We’re on the hunt for an RV that’s got all the safety bells and whistles, like airbags, side airbags, and collision/lane monitoring. If we ever feel unsafe, we’ll be saying goodbye to our RV and will replace it with rockers on our front porch.
We’re eyeing the Winnebago View 24T. With the generator or 960 amp battery and overhead bunk, it can carry around 880 pounds. But if we order it without the overhead bunk, we can save 120 pounds and have a payload of 1,000 pounds. We also have about 400 pounds we can put in our Maverick and still be under GCWR. Our trips will be shorter, and we’ll have to carry a lot less than we do in our Baystar.

I don't know if I would get too crazy about the carrying capacity. My guess it has very small storage bays and you'll be hard pressed to try and fill them to capacity as large/heavy items probably won't fit. 800 pounds is a lot.
Rather than carry a lot of extra/spare pantry items and other consumables, use to the Maverick to go shopping when needed.

If you get the 960 A/H battery option what is being provided to charge them?

OK, So I took a look at the Brochure.
"Dedicated 280-amp. second alternator to charge
coach batteries"
This is the kit they are using. I've serviced a few.
https://www.nationsstarteralternator...2-280xp-er.htm
This will quickly charge the house batteries even the 960A/H. That will give you overnight AC no problem. I see they are also including some solar. You may want an extended warranty or service contract with this.

Is there no diesel generator option ?
Also recommend you rent that size and see if your marriage is equally strong at the end of the trip. That model is the Murphy bed I think, has it's plus and minus. Definitely an efficient use of limited space. I have a friend with this layout in another brand. He says it's well liked by the boss, she can drive it and most importantly having your own facilities for travel is key to happy life.
