My batteries are about due for a change......anybody else make a decent maintenance free battery for these trucks? Like AC Delco? I have always had GREAT results from their batteries. Thanks.

1989 Toyota 4x4 xtracab SR5 V6, Beat to heck with 200k+ miles and still running strong.
Never used Delco, but have used the smaller Optimas, with mixed results.
If I were going to use Optimas today, I would go to the larger Yellow Top Optima with 900 CCAs also. They are expensive and require redesigning each battery box, but I suspect they are wonderful batteries. And very tough!
The 900 CCAs with these flooded heavy duty Motorcraft batteries would seem to be just what would be needed to really spin these big 7.3L engines, but I have not read much about their durability over the long haul.
Any additional input would be appreciated.
