Need a small breaker panel to finish Inverter Replacement

JFYI. The MS2812 is in and working great. Just used a two circuit sub panel as suggested and wired it up to jumper the 30amp to both legs then hooked up the two twenty amp circuits to the breakers.

Thanks for all the suggestions! Now am moving on to fishing a couple of cat 5 cables from the front to the rear of the coach.. that looks like lots of cramped spaces and probably plenty of blood letting to come!
