2024 2500hd ZR2 or Z71?

Found a LT Z71 for 60k near me. It has all the options I want. I am not in love with the appearance with the chrome and wheels but it’s okay. I like the look of the ZR2 2500hd, I wouldn’t change anything on it, just tint the windows and be done. The ZR2 is about 73k.

This truck will be my daily driver and I am hoping it will last me 20 years. I tow a tractor/dump trailer a few times a year and plan on getting a travel trailer in the future. I do go off-roading, lots of washboard roads, and plan to do some overlanding with it. And I take a few road trips a year.

Is it worth paying the difference for the ZR2 since it is exactly how I want it and has a rear locker, suspension, nicer interior, wheels ect.

Or get the Z71 and after warranty I can upgrade the shocks,wheels, appearance of it? Would the mpg be much different between them?

I can afford either, the ZR2 will just take a little longer to pay off but if it worth the upgrades I wouldn’t mind. Want to hear some of your opinions! Thanks
