I think the point to be made here is that while you can compensate for weight higher up to improve stability, you still can't beat physics and making similar changes while passing on the tent will always result in a more stable vehicle. Weight transfer will always be the enemy when dealing with off-camber trails and a low center of gravity is the best way to prevent having a bad day.
A bit of a rant incoming but while just a tent isn't going to be horrible, I think the issue is frequently that too many fall into the youtube/instagram overlander trap that they need all this shit and way too much of it ends up well above CoG.
I mean do some quick math... Take a 4Runner with a full-length rack (90lbs), tent (125lbs), 50" light bar (20lbs) , square awning (35lbs), and 4 maxtrax (32lbs) attached to the roof rack. Sounds reasonably typical for an overlander, right? That's 300 lbs. That's 20% of a 4Runner's rated (and substantial) payload above the roofline. Think about those who do this with an aluminum hardshell tent (180lbs) and a 270 degree awning... that makes it nearly 400lbs.
If you do a tent and just a 3/4 rack in that scenario you can be at 180lbs (minus OEM bars) which is much more manageable. If you can get away with just doing roof bars it's even less.
I'm always the asshole when it comes to rig weight and this is why. It's not just that people are piling on the weight, it's that people put this weight in the worst possible places.
