Sorry to have to say this but......that kit just isn't man enough for a camper split charge system. At just 15amp rating it will likely burn out within the first few months of use.
Typical camper leisure battery split charge systems will consist of two batteries...a starter battery around 64ah and a leisure 80 - 100ah. when both batteries are charged there will be very little current being switched between the two batteries but start the vehicle after a heavy weekend of discharging the leisure battery (lights/stereo etc) there will be an initial 'spike' in current draw of anything upto 40amps, quickly settling down to 15 - 25 amps.

Clearly a 15amp relay won't live very long carrying this much load.

If you are doing this from scratch then do it once and forget about it but you will need better hardware than you have bought.

Something like this: Note 70amp relay and 42amp cable.

whs ^^^^^^^^^^^^^

they are a waste of your time energy and money, 15amps isnt enough to power a fridge from ambient let alone charge a battery from anything less than not needing chargiing.
