Rot running higher

About a month ago I noticed my eot running about 10 deg higher than normal
I have edge cts to monitor while I'm towing. I haven't heard my fan kick on
Since this started. I put a paper towel in front of radiator and it doesn't fall down at idle. I was told possible the fuel filter need to be changed. So I tried to take the old one off its the built in filter and cap. This thing is welded on can't get it off. Broke two of the ribs trying to take it off. Any suggestion would be appreciated. I am in Florida for the week and have to drive back to sc on sat. I noticed if I stayed around 60 my egts were around 820 or so and my eots around 213 to 220. Also trans temp around 170 to 178 hit 183 a few times to 185. Does this sound ok. And should I be ok to make it back if I take it easy.

Not sure what you're towing but all of those temps are well within the normal ranges.

Temp are OK. I'd work on getting your fuel filter issues taking care of though.

Did you drain the fuel bowl before trying to take it off?

No I didn't drain. Shouldn't the fan kick on though. When I would hit 65 or faster temps would get up to 225 and little more when I would have to hit it to make it up a hill. Even when maintaing the faster speeds on interstate (65 to70). I remember the fan running previously just not now so I have to let off the pedal. If everything sounds ok though i will try and get the filter changed shortly. Thanks for suggestions.

Ok fuel filter changed. Still same issue we went down to beach going only 40 tops most 35 and egts were like 450 eot hit 200. Only took us like 15 min. Not towing anything. Will keep checking thinking no possible radiator issue maybe thermostat or hpop. I know it's hot and humid here so maybe me just worrying for nata. Just trying to make sure we get home.

I think you may be working yourself up. I just drove over three hours and intermittently hit between 190 and 211 (stop/go traffic after having been romping through long straights of highway) for my EOT. It was only about 85 ambient temperature here but this is the norm. Somebody else correct me if I'm wrong but if anything, your Tstat is working really well. I'd be worried if I wasn't reaching operating temps (Tstat stuck open). As long as your EOT doesnt get too hot (the numbers vary on many different variables), then you're good to go. If I remember correctly, these Tstats are meant to only fail in the open position. With this failsafe, the truck will never overheat.

Here, I even snapped a screenshot:
