I tow a 33' ~7,500lb travel trailer with my 2018 Expedition Max Limited w/max tow. It handles the weight fine, but can get a little unsettled in windy conditions. I started looking at trucks to replace it, but my wife really wanted to keep the third row for our 3 kids. So to prove to her all SUVs would have this issue I rented a Yukon XL Denali from Turo. It did much better with our trailer. The suspension was less busy and I didn't have to fight the wind nearly as much. It's not as good as a heavy duty truck, but it's better-enough for the 6 times a year we camp. My Expy has the base suspension (now with Bilstein 5100s) and the Yukon had magnetic shocks (CCD), so it wasn't apples to apples. The tow rating is lower (7,900lb vs. 9,000lb), but our trailer still fits in the specs. I'm cutting it closer on the payload and GCWR numbers, though.
One other big thing for me is the Yukon offers a four-corner air suspension. I love the idea of the suspension being able to level the rig when I put the 800lb of tongue weight on the back. I'm sure I'll regret it if it breaks while we're on a trip, though.
I was on the fence for a while, but I've had a ton of issues with my Expedition and ordered a Yukon XL last month. I love the Expy when it works, but it's been in the shop a lot. Cam phasers x2, both turbos, 6 shocks, ignition coil, transmission slipping into neutral on the road, sunroof, leaking rear differential, and more. The GMC dealer said theirs aren't perfect either, but I'm hoping the 6.2L pushrod engine will be more reliable than my EcoBoost. But I sure will miss the low-end torque of the EcoBoost.
Disclaimer: I have a 2018, the first year of production for the current generation. I know from this forum that a lot of the issues I've experienced have been addressed in newer models. I'm in no way hating on the Expedition. I just didn't have a great experience with mine and am looking for a change. But I still love it when it's not in the shop!
