Yes that's exactly the suggestion ... though I'd guess 10ga to be at actual limits around 250W in a typical 12V RV's wire length run. Certainly there are ways to utilize some parts of the pre-wire to achieve a higher power array, though it will likely mean splicing in larger wires and only using the prep-wire for a short span to eliminate pulling larger wires through the roof for example. Somewhat of a kludge IMO. Thats where YMMV comes into play...

Basically, a solar prep RV option is good for very nice battery maintainer systems but not much use when designing a "really usable" fully 12V solar solution. Wire gauge and run length are factors to consider. Wire should be considered when upgrading inverters too as I doubt the factory sized wires appropriate for 2000W if the rig came with 1000W.
