Belts maybe, I put new ones on and kept the old ones just in case of emergency. Diesel fuel lubricity additive, I use this because North Americas diesel is not the same(ethanol blend) and our old Injection pumps will thank you for using it. I also have a tow strap, of course to help people out on the trail that might be stuck. The only issue(knock on wood) I’ve had while adventuring the wilderness is the brushes in the alternator completely wore out and I was left with only battery power and no charge, I was able to get home on just that. If you stay on top of routine maintenance your truck will surprise you with its reliability. Change all your fluids to give it a good refresh and it last another 10 years(aside from your regular oil and fuel filter changes).
