As an owner of a previous-gen Nissan Truck, what I can say is that after 20 years, it will likely still look and drive exactly the same, all those hard plastic surfaces will still look the same, probably not crack, peel, or get sticky. And the seats will still be comfortable and it should still be reliable - it just might smell a little funky inside. I've been less than impressed by the interior durability in the nicer looking new trucks. When I sold my last Nissan truck, the A/C still worked, the transmission had never been opened and it was nearing 300K miles. The timing chain was wearing into the guides - so work would have been required at some point in the future, but, about 20 years of good service with only a few sensors and relays beyond routine maintenance. A lawn maintenance/handyman guy is still driving it around.
