24 volt solar panel recommendations?
Is this panel decent? Or is there reason to buy one of the slightly more expensive panels from Solar Blvd? Friend has Blue Sky controller capable of using the 24 volt panels. https://www.solarbl...

One of features - that cheap 20A controllers are usually lacking - is a remote display. This means, you not only have to route additional wires to and from that additional controller, but also mount it in easily accessible place where you can see the on-board display and push the buttons. In all but very big RVs it's difficult enough to find a good permanent location (in terms of both technical requirements and esthetics) for one remote-less controller, not to mention two of them.
Portable setup is a different logistics, you can use several small controllers, a milk crate placed upside down under the trailer - away from rain - will carry 3 or 4 of them, and a few car jumper cables will take care of wiring. That's what I did with my single controller before mounting everything permanently.
2*250W array requires 35-45A MPPT controller. 20A unit may or may not go up in smoke when hitting 20A limit, but some energy will be lost. If the OP is concerned about getting as much energy in winter as possible, it's better to get a controller bigger than 20A, to me this is a no-brainer.
