I would use the existing charge wire and place the DC-DC charger near the battery in the TC.
20 amp rating should be sufficient.
I think Ford has 30 amp breaker on its charge circuit, yet had a situation when deeply discharged 2 camper batteries would keep cycling the breaker and after 3 or 4 hr of driving/charging the batteries were still low.
The situation repeated when I got shore power as 40 amp converter was cycling as well and it wasn't till next late morning when finally the charge stabilize.
I researched B2B chargers for my boat project, where I add "house" batteries and have 30 amp alternator. I was hoping B2B could limit amperage to preset value, what happen to be illusion.
I finally ended with battery combiner and 20 amp automatic breaker.
All that with voltage meter on the cluster, so I will not get surprised the same way I was in the camper.
