Deep Cycle Battery Recommendation

I have two Trojan t-125's golf cart batteries and they work great. This is my second set as I sold my first TT with the first set and they were 10 years old and still going when I sold it. So it was a no brainer when I moved up to a new to us TT. In the spring since I added solar I will be buying two more to double the amps as we dry camp as much as FHU. The solar project works with 448 watts but with the two new batts Ill be adding two more panels.
