What size converter charger should I get?
Our vintage travel trailer doesn't currently have one, but it came with a marine battery that's rated at 85 Amp/hours. The smallest converter chargers I'm seeing are 35 amp. Is this small enough?

If the two produce different voltages, they will be "fighting" each other.
Go ahead and equalize two identical batteries (that have been used in parallel) at the same time and then let them sit disconnected on the concrete for a week. Measure the resting voltages to quantify the difference. Post your results.
For the OP: 35 amp is fine for 1 to 4 batteries.
