Tire pressure question

I have a 2017 F250 Lariat Fx4 with nitto grappler tires.
I usually drive with tire pressures around 60-65 in front and 65-70 in the rear.

I usually just tow locally so I never bother with changing my pressures. But I’m about to leave for a 8 hour trip pulling a 22’ inboard boat. Was just wondering if I should consider going up in PSI. As there seems to be a number of differences in opinion here, but the all seems to relate to 5th wheel or loads heavier than a boat.

Id just like to find a good balance between MPG and ride comfort. As my wife will be joining and she is pregnant. So road trips aren’t exactly comfortable for her.

Even adding 1000lbs onto the hitch (and rear axle), your rear axle weight will be lower than the front axle is day to day. 65-70 should be just fine.
