For now I will be doing mostly reliability mods and maintenance stuff. I do plan to install a 5th wheel hitch and make the subframe / box semi-easily removable. Down the line a small lift and super singles maybe, but I want to keep the truck stable, so that won't come until I've had a lot of real world driving with it fully loaded. If you have any suggestions for drivability / stability mods, I'm very interested.

It's never a bad idea to start with an engine monitor with an EGT add on. Edge CTS3 is what I'm using. Even if you plan on leaving the engine stock the monitor has a lot of useful information. Monitoring EGT is a good idea for a heavy truck especially if you plan to tow.For now I will be doing mostly reliability mods and maintenance stuff.

Upgrading the trans cooler is a good idea if it hasn't been done. Mishimoto has a nice upgrade for the 7.3L, assuming this is an auto trans rig.
An expensive mod but worth it IMO for a heavy off road truck are the Dynatrac rebuildable ball joints. They are pricey but once installed they can be rebuilt in vehicle.
None are required but would be good reliability options.
Dynatrac has a few things I would like to eventually do, the ball joints are already on the list when they need to get replaced, but I'm also looking at the free spin kit. If I ever decide to run super singles I would want to address the hub wear for sure, those big heavy wheels and tires will put a lot more strain on them. Steering is also something I'm trying to figure out, getting better steering feel and less dead space in the wheel would be awesome. Adjustable track bar, and replacing all the bushings in the steering will happen at some point. I really haven't started to dig into the engine bay yet but that will happen sometime.
At least I don't have to worry about the Dana 135, that thing is massive.
