Trailer Electrical Ground/Frame and Solar
The negative terminal of the battery goes to the frame via 6ga wire. And I think the AC ground goes to the frame when we're not off-grid. I'll wire the MPPT controller with two 6ga wires going to...

Marc-the-rogue is incredibly thorough when it comes to engineering and instructions. I would trust Rogue manual and run controller ground to common Neg bus, unless this complicates the design too much. With GFP or not - not sure.
Rogue 20 wouldn't handle 400W. Rogue 30 can do ~500W at sea level.
Yes, Rogue display on model 30 is nice and very handy, it saved me a lot of money on not buying a battery monitor. But my situation is different, rig is in Mexico and batteries are full 9 days out of 10. If you will or already have a separate battery monitor, you won't really need Rogue display with model 20 but you would have to buy a data converter for more accurate initial tune-up.
I was unable to find any 30A MPPT that was cheaper than Rouge AND had same features and options. Living there for months with solar being the only source, I can't afford a controller that is just "good enough". Don't want it to screw up my batteries because of poor features.
Panels - I tend to think there is very little difference between manufacturers though it's better to choose a known brand, wherever it's made. Buying panels in Canada sucks, there is not much choice of brands, or you pay fortune in shipping costs.
