What batteries did you replace last, how long did they last, how much did they cost, and what did you replace them with, how long did they last, and how much did those cost?
I can only fit Group 24s in my compartment. I’ve used Interstate, Sears, and now have NAPAs. The NAPAs are still going, but the other two sets lasted 5 and 6 years respectively. All were lead acid batteries.
New camper in November 2006. Original batts lasted about 3 seasons. Replaced with 12v similar to originals and lasted to about 2013. As I said, Interstate dealer in my town suggested 6v golf cart batts (MUCH larger plates) but they were a bit too tall. So I was able to lower battery tray and go back for the install. I have had those ever since.I generally try to keep them above 11.5 v when camping. No solar, so I use the genset for multiple day camp sites. I set up my new truck to charge from the alternator and it works well when driving. I have a Blue Sea Systems Automatic Charging Relay # 7610. Since it is bidirectional, I can charge the truck with the genset as well (never had an emergency though). When home, I plug the camper into 110v and the on-board battery minder does a wonderful job of battery maintenance. It even charges the truck batt when loaded thanks to Blue Sea. Some Forest Service campgrounds now have electric sites which is a bonus for us.
I don't have old data on cost. 2013 after all. I am sure they were more than replacement 12v but clearly it has been worth it given the extended lifetime that I have experienced. Those prices would now be out-of-date anyway. An interstate dealer, or any brand that does golf cart batts, could supply current prices.
It is mostly determining if you can accommodate the height.
