Converter/charger

We have a 26ft Keystone Cougar TT. Prior to that we had 2 Sunlines.I have a had a dual battery set up for years. With the Sunlines,I could go 4 days without recharging the batteries. With the Keystone,I have to charge them every day. I have 2 group 24 deep cycles. That is what I have always used.Since I have had the same set up for years, and got longer use with the Sunline, I assume the charger in the Keystone isn't as good as the ones on the Sunline. So my questions are, where is the unit located? I assume behind the fuse panel and ,what is a good charger to replace it with Thanks.

    An upgraded converter-charger is not a bad investment.

    A better investment is a battery hydrometer and a multi-meter with a current current clamp. I have a this Uni-T B4Q094 UT210E meter but there are many other to choose from under $100. With this meter you can check the charging voltage, the resting voltage and the amount of current being drawn when you THINK everything is turned off !

    It is unusual to to find "true" deep cycle 12V batteries. The most common true deep cycle batteries are 6V golf cart batteries.

    I doubt the converter/charger has anything to do with it. I would assume that the newer RV is using more power than the previous one. Additional sensors or systems?
