Hi Joe; the CTEK you're referring to has been discontinued. For the 4 batteries I recommend the NOCO GENPRO On-Board Battery Charger # NOC84FR. This is designed to charge/maintain 4 12V batteries simultaneously up to 230 amp-hours. This uses your standard AC plug and can be used with the NOCO AC Port Plug # 329-GCP1 if you want to make it easy to run an extension cord.
If you're trying to charge them while driving you would need the Redarc In-Vehicle BCDC Battery Charger # 331-BCDC1225D which works with battery banks rated between 75 and 200 amp-hours instead. I don't have the information on the amp-hours for your batteries so you will need to make sure they fall into the range of the chargers.
