Spare tire pressure
The four tires on my travel trailer specify 80 pounds each tire the spare tire only is rated for 65 pounds is this correct?

Depends what your trailer weighs.
Likely scenario, OE tires 65psi, hence the spare. Tires on trailer upgraded to heavier load rating when replaced.
The real question is do you need 80psi in your 80psi max tires or are they overinflated for the job they’re doing.
(With few exceptions, like the “.5s” , 17.5, 19.5, 22.5 tires, most all passenger vehicle and ST tires are fine to be used at the proper pressure even if rated higher. Side benefit, stronger, longer lasting tires)
