I used to tow professionally a number of years ago. Some things that I personally found that may help are...

I'm assuming your panel has barn doors (panels tend to have barn doors while the burbs typically had the clamshell). So no rear windows and the small windows in the barn doors limit rear view significantly. Now when towing infrequently this can be slightly annoying but a simple set of "extendo-mirrors" that you can clamp on when towing may be all you need. But if you tow frequently you may want to invest in a cheap wireless magnetic camera that will tie to your phone that you can use to keep an eye on your load and watch for hazards may a welcome safety feature.

Like said above, a trans cooler is cheap insurance. It may not be absolutely necessary in all cases but it cant hurt and it is cheap enough to be worth it.

And the last bit of advise I have is that you take extra care when doing normal maintenance and pre-trip checks. We can all get a little lazy on not checking oil, coolant, break, and other fluids all the time. Or not changing the oil exactly at 5000 miles (or whatever your regimen is). So before any tow just check everything, fluids, belts, hoses, tires, breaks, etc. before setting off. I know this seems like common sense but I cant tell you the number of times I saw a neighbor or friend set off on a towing trip without doing so and then get a phone call to come out and help them when a hose burst or fan belt broke and left them stranded when a simple check before would have prevented it.

Oh, one more thing... watch the wind. I notice your in S. Ca and the wind up in the desert, especially out in the areas between barstow, NV, and AZ can be difficult on trucks with a broad profile such as a panel, especially if you have any kind of trailer that also has a broad profile such as a toy hauler or camper. Its bad enough with just the truck but add a trailer into the mix and you can get into trouble quickly.
