The negative cable from the passenger battery goes down to a lug on the front of the engine block, then has a leg which goes to the frame. Almost looks like someone has replaced it before.

so not anything to be concerned about not being connected ?
I could not follow the cable from the battery to the block, but I did see a welder like cable running from the head to the frame
There was no broken eye under the bolt that holds that ground wire in, so it may be that was the location of the old wire
It dones't sound like there is sufficient reserve in those batteries, or they might not be fully charged. You can charge them and then get them tested for free at many auto parts stores. I've been using Walmart MAXX 65 for quite a few years, they are good and reasonable.
I would go through all the connection points I noted in the video. Adding a 1/0 cable from the engine block or head to either the drivers side frame ground or directly to the battery is beneficial. If you need to replace all the cables, CustomBatteryCable.com is a good deal. Also sold at XDP.
There are many reasons for this truck not to start well, but electrical function is a good place to start. If you are going to ask for help or need diagnosis, the best deal you can do is ForScan App for your cell phone and an OBD2 adaptor for the version of the phone. Total cost about $35-40, and you get very good quality monitoring. Many threads here and elsewhere about doing that.
A version is available for laptops. But I don’t have it. It’s very good.
Batteries are for storage, the question would be is your alternator is up to the task? If the batteries are being used because the alternator doesn’t supply enough, no batteries will hold out.
