Optima 6 cell battery ?

I have to replace the single battery on my Class C M/H. Does anyone have any comments on the new (?) Optima 6 cell deep cycle battery that is supposed to last twice as long as other traditional batteries? I know they cost about twice as much as other batteries but are supposed to be a lot better. We use our motorhome about 10 weeks a year. Thanks :)

Awesome product. They have more punch and recharge more quickly than conventional batteries. I use one in my F250 Superduty that I use to plow snow. I usually use two batteries because of the extra load of the plow motor and strobes but one Optima does the job. Well worth the investment if you only have one battery in your rig.
