Potential Coolant Problems - RAM 2014 1500 3.6L Crew Cab - PLEASE HELP!

I've had the truck for just over four years and its about to reach 81k miles. About a week ago my coolant temp gauge began to rise and fall between the halfway and 3/4 marks on the gauge, while my actual coolant temp fluctuates anywhere between 220-250 degrees on a hot 98 degree TX summer day. The coolant reservoir is just below the max level and seems to have plenty of coolant, so why is my coolant temp so high? No check engine lights have ever came on since I got the truck and this is the first real problem the truck has run into. Today I was also driving about 60-70 mph and the gauge nearly redlined before slowly dropping down in between 1/2 and 3/4 again. The temp never goes below 230 after getting warmed up, even when coasting at 30 mph, while the coolant temp seems to ALWAYS be much higher in comparison to the oil temp which stays around 215 once warmed up. Is this normal for these trucks? I know they are supposed to run hotter but 240/250 degrees for coolant seems alarming. I have not flushed or changed the coolant since I got the truck but there are no leaks or problems in the system to my knowledge at this point. Apologies in advance for all the questions, just a newbie here to this forum looking for some advice!

Your system definitely needs some attention fast before you damage the engine. My truck never goes above about 210. Have you ever added antifreeze to your truck? If you did and did not use the correct antifreeze you could really screw up the system. If you mix the wrong fluid the antifreeze will gel up and not cool/circulate properly. Seeing as it is summer you could probably flush the system and just put in some water to see if it corrects itself then later in the year redo it and put in the correct antifreeze.

Yes I have only had to add antifreeze once about a year ago after the reservoir had started to get low, but there was never a leak where coolant was visibly leaking from. I researched the correct type of coolant and used the Zerex G05 which is supposed to have the same specs as the Mopar coolant, and filled the reservoir to the max line. Does your truck have an oil temperature that is higher than the coolant temperature at all times? Im concerned with the oil temp being significantly cooler than the coolant temp in my truck.
