Batterry recommendation for Class A Diesel

Thanks for the recommendation but the coach batteries in our tradition pusher are 12 volt deep cycle group 27. Thanks

My EastPenn/Deka AGM batteries are going on 5 years old and they are all still fine. They are made in the USA. I installed the four batteries and haven't had to touch them since.
Make sure that after you install them that you set your inverter/charger for AGM batteries. Deka batteries

Rolls-Surrette S6-275AGM. 5 year warranty, 2 year free replacement, three year prorated. In my book they are the finest battery made.
