I just replaced a 2017 JKU with a 2020 Gladiator and could not be happier - to me it is the perfect overlanding vehicle. I have put just over 3K miles on in the 1.5 months I have had it including an epic trip to the Nevada desert and hill country. Longer wheel base gives it a much better ride and the creature comfort and space upgrades over the JKU are awesome. It feels extremely confident off road and I have had it on some difficult tracks; it is skinny enough to get through tighter trails where bigger trucks would get pinstriped (worse).
Currently looking at canopy/campers and the Alu Cab is in the lead.
I love mine, feel free to private message me any time if you have questions.
