Costco vs Sams Club 6V Golf Cart Batteries

I haven't had much luck with either the Sam's Club or Costco brand 6 volt batteries. Both have only lasted about 3 years. I use my RV on average about once a month (2-3 day weekend).
My set of Sam's Club just went out after 33 months. I originally had 2-12 volts deep cycle batteries and replaced them with 2-6 volt batteries from Costco after a friend talked me into it (the 12 volts were still going strong). Almost immediately, I wasnt very impressed with the 6 volt conversion because I( really didnt see much of a change in anything.
Now that another set has gone tits up, I will either pay extra for the Trojan T-105's or go back to the 12 volts?
BTW..I have a very good installed battery charger (Progressive 55amp)in my RV.
I found some T-105 for $125.00 and the Costco brand are $90.00 Not much of a difference.

Thanks of a real world example.

Never have found where two 6v is better than two 12v DC batteries of the same quality/rating myth came from.

In our case same battery rack holds the both starting and house batteries so going tall is not a real option plus if we loose the starting battery or one of the house batteries due to a dead short, etc we just move aroung cables and keep traveling.
