I bought new tires for the truck switched from the P rated that was on the truck when I bought it to LT tires. New tires are rated for 80lbs pressure. Question: Do I run the tires at 80lbs all the ...

The E-load tires you now have only need little more pressure then the P-tires wich are B-load tires with pressure needed for the maximum load of 35 psi.
But when you search for the pressure advices, on same plate is mostly the Gross axle weight ratings ( GAWR) and GVWR ( V for Vehicle).
Then read from tires the maximum load ( googled and found 109 Loadindex wich is 1030kg/<>2260lbs a tire for P tire in 245/75R16) and check if it gives AT 80 psi on sidewall.
Then to make it complete give speedcode ( probably Q for up to 99m/h)
Then I will calculate the needed pressure for you with use of one of my made spreadsheets , In wich I use an even saver formula then the tire-makers use. Also with some reserve for towing.
I expect the outcome to be as low even as about 40 psi rear when towing. Front then can be even lower because GAWR front is mostly lower then rear and when towing front axle is lifted up a bit by the weight on the pin.
