So when I pulled the trigger on a GM full size, albeit mine is old...(2006) lol, I came from a 2001 Dodge Durango limited. It was a Major adjustment. Like going from a pinto to a bus! Lol. But I got used to it and maneuverability is no problem. I trace down to Los Angeles and Orange County California often and working really isn’t a challenge. Over the last 6 years I’ve driven all the one ton pick ups and the all the SUVs that make up the fleet of vehicles my best friends parents own, while either house sitting for them to take care of the animals while they travel, working for them at their recreation businesses or traveling with them. Always have to remind myself how hard it is to turn a one ton crew cab. Especially into or out of a parking spot! Lol. But to the me Denali is way easier. They have a 2015 escalade ESV, and just picked up a 2020 Yukon xl Denali in April. We went to dinner a few weeks ago together and I was asked to drive us home afterwards because I hadn’t had anything to drink. We got in the XL Denali, and despite the fact it’s quite a bit longer than my 2006 XL Denali, it was still so much easier to handle and maneuver in and out of the parking lots than the one ton crew cab trucks. The camera system is great. If you have multiple kids, and they’re in sports, get the XL! You won’t regret it! I went through the same thing considering making the move to a GM and at first couldn’t justify an XL. But after 6 years of ownership, tons of space in the back for all my auto detailing gear, sleeping in it with an air mattress back in June on a camping trip, that I wouldn’t have been able to do in a standard wheel base Denali, or hauling my sisters three kids around, I definitely DO NOT regret getting the XL over a standard wheel base. Lol.
