This will work if you have a propane grill port on your rPod:

A search on Amazon for 'blackstone propane' will give the above, as well as several other options.

Hello and welcome!

I am assuming by Blackstone, you are talking about a Blackstone griddle. It should come with what you need to connect to a disposable tank, but if you want to use a 20 lb cylinder, you need one of these:

This is the link for the better quality steel wrapped hose. If you want to use it with your RPod's low pressure fitting, then someone else will need to provide the answer as I don't have a low pressure port in our 2016 RP179.

Yummy! I can smell that from here!

I can agree with that.  Just want to make sure that the poster knows that the auxiliary LP port is not a complete waste.
 

But the r-pods without the optional outdoor stove that come with that port mounted on the frame, by itself, well, thats a lot less useful without buying a dedicated appliance and connector or two. Much simpler to just buy an off-the-shelf camping stove and use that...or so it seems to me. 

Again, just my opinion.

Our 195 has that port in conjunction with the outdoor stove (which slides out from the pass-through) and it works great (and is very handy).

On another forum I visit, someone just bought a brand new 2021 $150,000 class B, got the 'bum's rush' from the dealer and they don't know ANYTHING about it. 

Holy smokes.

BTW that LP port on the frame is almost worthless. Forget it is there. Seriously.

If you want to cook outdoors, just buy a tabletop or freestanding grill, screw in a bottle, (or attach a 20# tank) and go for it. If you want a small propane firepit or lantern, again, just provide it with it's own LP supply.

If you use that frame mounted port you have to use a portable LP appliance that does NOT have its own regulator. Try finding those at a big box store.

And if you do, you will be draining the supply on your trailer. Just....fo-get about it.

My opinion and of course, there will be other opinions to follow. 

I believe the port is not for connecting to an external propane tank, but is instead a port for connecting a grill. It is low pressure so you would need one meant for low-pressure propane. These don't have (or need) a regulator since the pressure has already been reduced by the RPod's regulator. Our 2016 RP179 does not have that. It would be handy and I have thought about trying to add one. I just have not figured out how yet.

As for the battery, yes. The converter in the RPod charges your battery if low and maintain it at a float charge if it is fully charged. I added a 30A outlet to our house to be able to keep the RPod plugged in and also to be able to run the AC while we are home. Most of the time, I keep it at 80F because I don't want the interior to get too hot and I don't want the NC summertime humidity. In the winter, I can keep a small ceramic block heater going to keep the interior above freezing. That does not take the place of winterizing, but it keeps my LiFePO4 battery above freezing since it is inside.

1 - Does having the Rpod plugged in charge the battery?  

2 - I noticed there is a port on the front of the frame tied in with the propane line.  It has a blue rubber cap on it and a valve.  Is it for connecting to an external propane tank?

Thanks,
