3 stage charger for true deep cycle battery (Trojan T-1275)

I am expecting to replace the 12V battery in my TT this year and would like to go to a true deep cycle battery like a Trojan T-1275. This battery has a lot of power, but it has some "unique" charging...

While researching this I stumble across the US12VXC deep cycle battery from US Battery. It is a Group GC12 (like the Trojan T-1275) but has more "reasonable" charging voltages.

Bulk Charge - 14.7V
Absorption Charge - 14.7V
Float Charge - 13.02V
Equalization Charge - 15.3V *

* Constant voltage extended for 1-3 hours after normal charge cycle (repeat every 30 days)
