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?

Consider that a 12VDC battery will demand 17-20AMPS DC CURRENT if you hit them with 14.4VDC Boost Charge voltage whewn charging. This will give you a 90% charge state in a short three hour time frame and then you can reuse the battery again until it runs down to around 12.0VDC...
If you ever plan on going with two batteries on your trailer than you should get a 45AMP Converter/charger unit as both batteries will then demand a total of 34-40AMPS DC current when hit with 14.4VDC boost charge voltage....
You want your battery to make it through at least ONE NIGHT on a battery run and then if you have a 2KW Generator you can hook up your trailer shore power to it and get back in business again for the next day/night run off your battery...
ALot of places will camp at have generator run time restrictions so you want to get your batteries charged back up to their 90% charge state as soon as possible.
