2014 F350 6.7 Question

Hello all, I am new to the diesel world. I have a 2014 F350 lariat 6.7 with 155k on it. I have noticed the last two times we have went camping that when I am towing up a mountain my truck starts to over heat. The temp gets up to 245 degrees, which is almost 3/4 of the way up on the temp gauge. The transmission temp stays about the same so that makes me think that my truck isn't being over worked or anything and it only happens when I go up hills. My camper only weighs 6,500 lbs. so I wouldn't think that would cause any issues and I don't try to run the truck hard up the mountain. What could this be? I had an F150 that started doing this (without towing) and it turned out to be the fan clutch that was going bad. Could that be it? The truck is completely stock. Also, I have noticed that when I step on the pedal the turbo will go up to 20 psi, but I don't really feel like it's got as much power as it should because it takes it a while to pick up speed and I don't feel like I have "on demand power" if that makes sense. Is this normal for this year? If not, what could be the issue here and how do I fix it?

Are you using Tow/ Haul mode? Even pulling my 3000 pound trailer, the trans will not kick down early enough for decent grades. This increases EGT and oil temps pretty quickly. Kicking down from 6 to 5th gear cools things down.

Tried both ways with and without tow/haul mode. Couldn't really tell a big difference either way.

Sounds like something blocking the radiators. Have you checked your coolant levels? Our trucks have stock radiators with plastic endcaps that will crack and leak.
