Trojan outpriced their value decades ago.
About 20 years ago I camp WITH bus conversion. Had 4 batteries for house bank. Bought $46 batteries at Sam's and could use camper for 3-4 days before it needed recharge and that included 1l of coffee brewed every mooring.
They gave me solid 10 years of good service and I was still using couple of them on year 12.
Right now golf cart batteries run $110 at Costco and I will be buying them this spring for my cabin.
I have a pair of 12V 206AH lithium iron phosphate batteries giving me 5260 watt hours, they can be run down to 95% discharge many 1000s of cycles. I can dry camp in deep shade for over a week only using about 50%, and that includes running a 6.3 cu ft 12V DC compressor refrigerator freezer. I also have a 2000W pure sine inverter but I try and minimize use to short things like grinding and brewing coffee, and the wife's hair dryer.... My little 21 ft trailer also has 360 watts solar, which can generate around 2000 watt hours per clear sunny day....
