The advantage of multiple panels is higher voltage output by wiring them in series and this results in less current loss going from the panels to the battery bank. With the panels wired in series any shading of a panel will reduce the output from the entire array in the series so parallel is better when one of the panels will be in the shade.
With an RV the space is limited and full size panels, like the ones used on homes and commercial buildings will often not fit and the dealers will not sell them to you in the first place.
You do want to match the Voc output for all the panels and keep it within 0.5 volts as it will maximize the output and efficiency of the MPPT charge controller.
