With a pair of GC-2's from Costco, assuming they aren't dead... You have about 206 amp hours at 12v. A MegaWatt or a Meanwell, set at 14.8V, with an RC charger meter in line, will get the job done to an 80 to 90% charge faster than most anything else. 1.5 to 2.5 hours if discharged to 60% SOC, should get you back to where solar can finish the rest.
I would look at getting a RC watt meter off of ebay, and when at 14.8V, the charging rate drops off from 30+ amps to a 10 amp rate of charge, I'd shut the generator off then. Your batteries will be fine. Keep an eye on the water level when doing this.
I've done this many times with my Trojan T-1275 150 amp battery, with the $50 30 amp MegaWatt version, set at 14.8v. Works like a charm. Use 8 gauge wire for the connections. A Honda Eu1000i will run the 30 amp version, it will not run the 36 amp version, you need a bit more generator for that.
The objective when doing this is but one... while dry camping, bulk charge your batteries as quickly as possible with least amount of run time on the generator. Absorption and float charging can and should be done with solar panel setups.
