The debate isn't about which is "better," but which fits your behavior. Do you park in the shade to keep the RV cool? Or do you want a set-it-and-forget-it system?

Roof Mounted Solar

Best for: Convenience, stealth, and travelers who move daily.

Portable (Suitcase) Solar

Best for: Boondockers who stay in one spot and value AC/comfort.

The Verdict

For serious boondocking, we recommend both. Max out your roof for travel days and base loads, but carry a 100W-200W portable suitcase to deploy when you find that perfect shady spot under an oak tree.
