Any upgrade the solar in a 190?

The standard utlitiy solar modules are around 300-350 watts and can be bought for about 50 cents per watt now, so they are very cost effective. The other benefit is that there are no holes in the roof, you can mount the module from the side to a vertical plate which is in turn mounted to the side of the top edge of the trailer. This also allows the module to be stood off the roof a couple of inches for better cooling of both the module and the trailer.  

I haven't done this yet but my plan is to remove the a/c and TV antenna and mount 3 modules up there for about 1 kW of solar. 

I handn't seen that one yet furpod but it could work. It has an EER rating (BTU/watts) of 5000/700 or about 7. It would be more efficient than the indoor portable a/c's but about the same as the RV roof a/cs. 

I've been thinking about a 9000 BTU minisplit like this:

These have an EER of about 15, so use half the energy.  Plenty spendy though. The evaporator unit on some of them is small enough to fit above the drivers side front window above the bed in the 179 and the condenser would go on the tongue where the batteries are now. I don't think there's any practical way to carry enough battery capacity to last overnight using lead acid batteries so I'd need to go with lithium ion. About 4-5 kWh worth. More $$$.  And then I need an inverter, and about 1KW of solar, and a controller for the solar, etc. Using salvage Tesla batteries I think I can do the whole thing for about $3.5- $4K if I'm lucky. Here's a guy that's done everything except the a/c on his full time RV.

I don't recall exactly the width of my rPod but they vary slightly anyway so you should measure yours. If you want to use an rDome I'd suggest taking the keder rail (the rail that an rdome would slide into) on the passenger side of your pod loose and sliding the plate you're going to mount the solar module to behind that, so measure from that point. 0.080 inch aluminum plate should work fine, just shoot several self tapping screws into the top 1 inch of the pod wall and into the module end frames. You can cut the bottom edge of the plates to match the curve of that section of the rPod.  If you want to get artistic, maybe even curve the top edges of the plates so they cover the module edges.
