6 Volt RV batteries

I have been a fan of Trojan batteries for many years. I have a 2005 Alpenlite and use a bank of four batteries. When the trailer was new I installed a set of T-105s that lasted about 7 years, and I installed a new set. It seems to be time to replace them again as they won't stay charged above about 12.1 volts. The only issue I have is that the Trojans have gotten SO EXPENSIVE. What I'm wondering is whether there is another brand/battery that is reasonably priced and dependable.

    An amazing statement! If they took a long time to get that bad, and you kept using them till now, then it would seem you might only need one 12v battery to get the job done. Why buy four new 6s if you only actually need one 12v batt?

    This is all very peculiar!
