Are the batteries in our trucks the 24 or 27 series size? I can't find the information anywhere. Thanks guys....

The original batteries should have been Group 27F.

Much better replacement is either Group 30, or 31.

They will fit the battery trays with no modifications and are much stronger.

My Interstate catalog shows Group 65, which is not to say that was OEM. Unfortunately the aftermarket tends to spec "close enough".

I have group 65 1000amp wallyworld batteries in all the trucks.
