FYI some pointers what new truck gives you beside mechanical warranty.
Just today I drove 340 miles and traffic-monitoring GPS advice me about 48 minutes delay in front of me, while giving me option how to detour it.
When mapping can still be done with paper maps, you will not get the feature on older truck, while using your android while driving might bring some issues.
- tpms saves you about 10 minutes every morning and let keep your hands clean
-cameras, so you don't have to get out to check what is behind you, or how far are you from the curb
-remote start, great for coming back on those 120F parking lots. That thing will start truck who I can't see yet. Have to really test it some time, but I think 1/4 miles is good estimate.
-instant mpg and distance to empty. Pretty accurate with 0.2 mpg error on my truck. DTE obviously will change with road condition and speed.
-darn truck will even tell you when light bulb in camper tail is burned out.
-blind spot warning is obstructed by camper wings, but still works to some degree
Some might say those are gadgets and I could agree, but those gadgets give lot of pleasure, while saving time and increasing safety of travel.
