If a player CV is "parked" not moving, by the same players BA, allow the player to connect the CV to the BA power output via wi-fi "connect" (In a similar way you can connect to a cargo container currently). This gives another purpose to the BA and potentially allows the player to leave the CV powered up and gain some benefit form solar cells that are found on a BA or leverage the massive storage tanks a BA can support. In particular this would enhance online server players, who could leave their CV powered up with just the fridges and grow lights on - removing the worry of offline, total fuel tank drain and loss of fridge contents etc. - After all if you can plug in your real world Caravan to home for power now - this would not be a stretch for future home bases.
