MissBehavin,

I believe that the two engine starting batteries in your TourMaster are Group 31 batteries with around 1050 CCA for rated starting capabilities. The high cost name brand 'maintenance-free' batteries such as Optima in this size/rating can easily go well over $300 each, and even the Sears DieHard version is over $220 list. That is why the PowerVolt from Freightliner is a sweet deal. I don't mind checking the water on this style of battery, and can expect to get nearly the same service life from these as from their 'maintenance-free' cousins. The CCA rating of these under $85 batteries is as good as or better than the AGM Optima batteries and the total AH is quite a bit more...so I pocketed the few hundred dollars in savings from the pair and stayed several days at a very nice "resort" class park on the Oregon coast instead with the money
