What we prioritize
A vehicle changes which specifications matter. Twelve-volt output feeds the refrigerators and accessories already wired into most rigs without a conversion penalty, and expansion capacity is what turns a weekend setup into something that supports living aboard. Either property admits a station here, which is worth saying plainly: this is a union, not an intersection, so a large expandable unit with no car socket sits alongside a smaller one built around its DC rail. Both properties are ones the general rankings ignore entirely, which is why this cohort looks nothing like the flagship list.
