460 watt solar setup: wire sizes?
I want to change out my old 50 watt panel and 10 amp controller with at least one and hopefully two 230 watt 24 volt panels and whatever controller would be best. Right now the roof on my fifth wheel ...

Hi
Yes 10awg will work fine for a 48volt array
Even if you hook the two 230 watt panels in parallel for a 24 volt array no need to change out the 10awg wire. 460 watts at 24 volts the most you will see is 18 amps if you go in series as I would you will see half that current from the array to the controller.
What MPPT controller are you looking at - there are several good ones on the market - My preference has been the Morningstar line - IMHO they are the best you can get. Oversize the controller you might want another panel in the future.
