limited

Hey all, My DW & I just purchased a, new to us, 2019 F450 Limited 4x4 DRW 6.7 PS to haul our 2012 Lance 1191 truck camper. For a number of years now, we've hauled a 02 Lance 1130 and the current 2012 Lance 1191 on our 07 Dodge 3500 4x4 DRW 6.7Cummins and loved it until it quit. Long story...

I have a 2002 Ford Excursion Limited with the 7.3 liter turbo diesel, 128816 miles. The truck is Black with Tan accents, a tan limited interior, and tinted windows. Front and rear bucket seat, heated automatic front seats. All of the seats are in great shape, there no rips in any of the seats...

Is changing the fluid in a t case like a transmission in how in a transmission, if it hasnt been changed before, don't do it? Because im not sure if the t case fluid has ever been changed and i want to do it. Same with the differentials. Are they that way too?
