To keep things simple if you have a single stage charger in your MH you can always just buy a 40 amp portable that has settings for wet cell, agm and gel battery. I have an old Magnatech 9050 single stage charger in my MH and use a 40 amp B&D portable to charge, equalize and desulfate. I charge my 2 6v GC batteries in Oct when I winterize and push the battery disconnect switch for the house batteries and disconnect the neg cable on the chassis battery then fully charge again in April. Just checked the voltage and they are at 80% SOC. They only lost 20% in 4 1/2 months. I don't keep them plugged in 24/7 even in the summer, just recharge when they self discharge to 80%.
