IMO, you don't really need the Lucas oil additive.
If you see BITOG, there is some fact finding there that your truck may not need.

In Dallas, TX, you probably wants to use 15W-40 for the summer.
It will give you better protection in the summer heat.

I think you have a lot of great upgrades already.

Where is the PMD at?

I run 15w40 in the summers. I'm in New York right now, for the remainder of the year - so I went with the 10w30.

There isn't a PMD in the 1993.

Does the truck have ABS? If it does, all the more reason to keep the fluid fresh, keep moisture out and replenish the corrosion inhibitors in the system.

Even if it does not, suctioning and replacing the fluid and bleeding the brakes will ensure good clean fluid at the calipers and rear cylinders and thus longer life.

Not sure if there's a specified interval there... maybe every couple years or 30-40k miles.

Also, don't forget the radiator cap. Critical to maintaining system pressure.

Ever replaced the oil breather?

Might be worth it to put a pressure gauge in between the filter manager and IP to ensure good LP performance. A lot of people run a pre-filter and an upgraded aftermarket lift pump since the factory ones don't seem to supply what the IP can use. The '93 model lift pump is the highest output FACTORY model from what I have read and it's best to use OEM parts there since other suppliers can build it cheaply and with less winding on the driver without informing you.

I believe Kennedy sells an HD lift pump and the stock replacement.

what balancer did you use?
ATF flush? do you mean with a machine? bad form... Drain, change filter, refill. better in my opinion.
