dual batteries help

Ok so ive got tj that i just put tnt tubes on, i had the mean green dual battery tray and some older blue optimas, now with optimas now being junk i need two new batterys and dont know what to use, ive seen the diehard p4 is the best but a) can i fit two of them b) is one puting out enough power like theres two, I can swap to a high ouput alternator thats not a problem but clearence with the dual batterys right now is a real mess so id love to say with on battery, im running cb,radio,winch,arbs, york oba pump and electric fan so im wondering if this is to much for a diehard p4?

one deep cycle should be fine. a lot of people that upgrade to dual batterys dont really need it but it is nice to have. if running a single battery you might want to plan on a high output alternator. my buddy has a mean green and says he saw a noticable difference running a deep cycle with that alt. compared to the stock setup. i plan on doing this eventualy
