The OEM batteries in our truck are just past 5 years old and likely are nearing end of life. Should I bother testing them or just replace? If you think I should test them, please recommend a good automotive battery tester.
Recommend battery tester for group 48 batteries

I have both the "fancy" and the carbon pile testers, and I prefer the carbon.
They're all from the same factory, so here's a sketchy one from Aliexpress.
Obviously disconnect your interconnects so you get results for each individual battery, no matter what tester you use.

Carbon pile tester is the gold standard, but these work decently enough and highly rated by users and the Project Farm guy, if you want to search for his review on testers from a while back on YouTube. Ancel BA 101.

Simple to use as well. I have purchased at least 8 of them and give them out as gifts to family and friends.

This TOPDON BT 200 is great if you want to splurge. The ANCEL BA101 is good at half the price. Both might be on sale for Prime Days next week.
I have the Ancel, which was cheap (<$20 at the time), and does provide some data.
But keeping in mind its limits as a conductance tester, the conclusions it provides are no better than the simple household battery testers with the green/yellow/red scales to indicate the health of a cell based on its sole measurement of unloaded voltage.

I bought the ANCEL a couple of months ago on BITOG recommendations. The numbers it generated were very close to what the Batteries Plus tester and a parts store tester showed. Be aware it's very sensitive to a good solid contact of the clip on the battery terminal.
I also have the Ancel tester, paid $<20 and it works quite well. Sure there not a carbon pile tester but there quite accurate for what they are especially with a little knowledge.
Likely the most telling piece of info they give that most ignore is the internal resistance. Generally your looking for <5 milliohm. A little more is OK but much past and the battery is likely too sulphated for long term continued use.
