I would say it is rare to get over 5 years with typical lead/acid 12v batteries.
I averaged about 4.5 - 5 years, and that was taking them off the TT during the winter and putting them on a trickle charger.
Ditto that the more deep discharges that you do, the shorter time your batteries will last.
If you are going to boondock, consider an Olympic catalytic heater to save juice, as the forced air fan takes a lot of amps out of your batteries. 6v deep cycle batteries have higher amp hour ratings than 12 volt, meaning they will supply you with more amps, and they should last somewhat longer too. IF you can keep from frequent deep discharges, then yes, you might get 7 years.
Keep in mind that as batteries discharge, sulfate builds up on the plates, and as that builds up, the batteries give off less electrons and slowly get weaker.
You are doing something wrong if you are not getting more than 5 yrs from a battery.
Most likely you do not have enough battery capacity and are drawing your battery below 20% DOD for GC batts or 80% for Marine/RV combo batteries.
GC batts are designed to handle deep, deep discharges and still give a longer life than Marine/RV combo types.
So far I am now at 6 yrs on my GC batts and I use them to power a home fridge while traveling and overnighting. They most likely will give me another 2-3 yrs.
