Engine battery recommendations

Hi everyone. Any recommendations on an engine battery replacement? I don't see any specs in the owners manual. I bought a 2003 itasca sun cruiser, only 40k miles on it, but the previous owner, had it a year, and didn't have any history on the vehicle.

I thought about trickle charging it, but it looks pretty rough, thought I'd just start fresh.

I can deal with the house batteries later, they're ok.

2003 itasca suncruiser 35u

Thanks in advance

    I'd get the biggest meanest battery that will fit the available space.

    Eskins,

    Things you should know...
    Most 35Us were on a WorkHorse Chassis and were either a Ford 6.8 or a GM 8.1. As both are gas engines, any good starting battery that fits in the space will work for you. Look at the battery. It will have a number on the top like 27, 27F, 34-72 or the something, write that number in the owner's manual. Just match the number.

    Before you do that, is the battery bad? Charge it, let it sit for a day. If it cranks the engine, it is good. If it seems bad, clean the terminals and try again.

    What chassis is the rig on?
    Ford would normally be an F-53
    Workhorse could vary on chassis model.
