Due to the very poor selection of DC appliances and often their RV bloated price tags, I have opted to keep AC, but generate it locally. Instead of buying a DC to DC supply for a laptop to get 19V for about $100, I bought a 1KW inverter instead for about the same price. If I don't want all my lights to be Fluorescent Cool White in color, I can use the 9W 3K bulbs instead in a warm white with high Color Rendering Index >94%. Try it. Try to find 12V RV bulbs that are not Amber, Red, or Cool White 6K. Most of the outlets in my RV are running off the inverter. Only the kitchen and bath loop are still on traditional shore power or generator along with the AC. This limits the generator runtime where shore power is not handy.
I have not trimmed my home use enough yet to cut loose from the grid. Heat pumps and long wet winters on solar just is not a match yet. They haven't fixed the solar when the sun doesn't shine problem yet.
I don't have to mess around with trying to adapt everything to 12 or 24V. With a good size deep cycle battery, even normal microwave oven, blow dryer, other short duration high amperage loads are possible that is simply not an option on DC.
