... torn between getting the XL or Standard.
We are a family of 4 that also totes my two nephews around a few times a month.
We also do a lot of road trips in our 2011 f250 diesel.
I'm keeping my truck, the Yukon will become my daily driver and road trip vehicle.
Should I do the XL or Standard?
Note my profile hints at where I'm from.
I used a Yukon XL as a NYC livery driver for five years.
In NYC, parallel parking a 19 foot long vehicle ain't easy.
In NYC, EVERY garage charges a $20-or-more surcharge on top of their standard rates for vehicles this big.
It was often enough that I had 3 riders and their luggage / equipment, that a Tahoe would have been a liability.
You said 4, possibly plus 2 nephews.
Since your profile doesn't say, I'll guess that where you're from, it's easier to find parking than in NYC?
If I had a family with 2 kids - nevermind 4 possibly plus two more - a Tahoe would NEVER cut it.
XL, without question.
