Go back up to Robins first post andcheck my answer as believe I reflect the same considerations.
Battery Acceptance .Correct Cabling
Temerature Compensation.
Maineys point is also a good one as the cabling from any charge source to the Caravan regardless of smart or not is critical to what voltage gets to it.
Locating a small smart charger at the front of a vehicle with the battery being charged at 6M away unless the smart charger has the capacity to compensate for voltage drop from undersized cable then no way will 14.4V get to it.
Some smart chargers are designedto compensate up to 1.5V drop but I find it better not to mention that as it is agreen light to reduce cable size and still stuffthe system.
That has already happened with the zero volt drop splitter where onechap said you beaut I can use smaller cables .
For the littlle bit extra copper and cost oversize do not undersize as prematurely failed batteries far outweight the cost of correct cabling to start with.
