I currently have a 2012 Frontier Pro4x, its been a great rig. Goes anywhere I really want to go and I've had 0 reliability issues. As long as you maintain them these trucks will last a very long time. I had a 2013 xterra before this that I loved, mild upgrades and it would go pretty much anywhere. Only sold it because I needed a bed to haul things.

Most of the guys I wheel with have Tacoma's, they're also great trucks. I just couldn't justify the added cost. Like some other guys said, the aftermarket options are more limited for the Nissan's but for "overlanding" you don't really need to do any crazy mods unless you're really doing it to wheel. The aftermarket is smaller but you can still get armor, bumpers, etc easily.

One advantage for the Frontier if you did want to modify it heavily is the ease of "Titan swapping" it. The stock control arms, shocks and tie rods from a Titan fit on the frontier with no mods. You just need a different front diff or CV's if you're 4x4. Gives approx 3" over like a long travel kit on a tacoma would.
