You are pulling with a Suburban so what I do is not an option for you how ever I will describe what I do for the benefit of all.
I use a โ20amp Smart Charger around the farm year round and we have a 2000 Yamaha gen/inverter.
I fished an extension cord from the 4 - 6 volt batteries to the fifth wheel hitch. I set the gen on eco in The back of the truck, plugin the charger and clamp to the batteries.
If we use the furnace all night while boon docking on the road the house batteries get charged properly as we cruse down the highway.
A heavy gaged wire from your truck battery to trailer batteries may take out your alternator.

Yes I do get that a DC to DC converter should do what I need. But those seem to be hundreds of dollars.
Thanks
Here is one that does up to 15 amps for about $30 bucks.

About 200 watts of solar on the roof of your trailer will keep your batteries charged when traveling down the road.

I run a 2 gauge dedicated run between my truck and trailer and use Anderson connectors for the link at the receiver.

Thinking about wiring gauge and voltage drop, do I then have to mount the dc to dc charger at the back of the Suburban so it's close to the trailer? Or can I mount it up front and run a 12 or 10 gauge wire back to the plug? If I mount the charger in the back, do I need to run a 12 or 10 gauge wire to feed it? I think oldwizard kind of answered that but I want to be sure.

Start by running a heavy dedicated charge line between the truck and trailer. It will help in trickle and maintenance charging. If you want more, later you can add a DC to DC charger off this new run line.

The point of the DC-DC converter (charger) is such that you can ignore the voltage gyrations of the alternator and any voltage drop in the wire and get proper charging voltage on the trailer battery. You no longer care what the vehicle is doing or how it works.

Or put another way, even though the trailer battery is needing a strong charge, the alternator is only putting out enough to float charge?
