Not 19.5's but I bought some Cooper Evolution 295/70/18 M/T's tires last summer. Load cap: 4080lbs. I bought them due to the higher weight and to put me at ease. LoL
Put about 1K miles on them from SoCal to Lake Powell. White knuckled ride the entire time, to and from. They felt as if they were walking around. Couldn't drive any faster than 60ish mph. 65+ and they became very mushy-feeling is how I would describe it. They wandered and pushed around a lot when correcting the wheel. If I over-corrected, they would get squirrelly and wander almost into the next lane. Never stable, nor comfortable unless driving well under 60mph. I didn't feel in control. Not sure if it was because they were new or because the aggressive tread lugs or the taller sidewall. My wife observed me the whole time saying when we got back home that she never saw me hold so tightly to the wheel as did with these new tires.
Did I not give them enough time to break-in? Replaced them with Cooper ATP's when we returned home. I really wanted to like them as they were great in sand, just not on the hwy, loaded. Unloaded, with the camper
off, they were fine.

This is what tire manufacturers website will tell you.
Other tires have min inflation as well, although I watch "Matt's recovery" on youtube and he drops the pressure to 5 psi for blow sand on his Jeep. Than he pulled the tire out of the rim on couple of occasions.

Except 19.5s aren’t normal tires with normal beads. The tires will come off the bead way before you have the pressure low enough unloaded to be “correct” for a empty bed truck. So, using a chart for the minimum is fine as long as you aren’t worried about coming off the bead.
You don’t have to believe us though buy a set of 19.5s, go to a beach, and air down. 😉 The beach isn’t really required, but that’s when people usually find out that they can’t air their 19.5s down. 😄

Weigh your axles loaded and unloaded then go to the tire manufacturers website checking the column for your tire width. Most of them have an inflation guide for different loads. These can vary quite a bit among different tire brands. There is no one-fits-all pressure among different 19.5's. I run my rears at 50psi empty and 110psi loaded.

Is 80 PSI really considered low??? What do you recommend?

Tire pressure too high may have the same effect, especially on the front wheels.
