New Chassis Battery time Cat C7

I need to replace my engine batteries for my Cat C7 the batteries in it are group 31 1000 CCA these are just chassis batteries I have a separate bank of house batteries. Any recommendations for new ones at a decent price?

After reading some info in another thread I checked and my chassis batteries do not charge when the unit is plugged into shore power. I ordered a Mega TRIK-L-START charger that was recommended in that thread, I will be adding that with the new batteries.

    A good source for Grp 31 batteries is heavy truck dealers.

    Go get the Interstates at Costco. My first set lasted seven years and would have gone longer if a stupid shop hadn't left things on for a week. Might call an Interstate Distributor and see if they'll have any Independence Day sales and Military discounts. Last year the distributors were cheaper with the special sale than Costco was.
