I just returned from a long 4300 mile road trip through 7 western States. I also used the select shift in the mountains of Colorado, Utah, and more. It worked flawlessly. I was carrying a bunch of gear in the back, so my expectation of performance with a 4 cylinder was pretty dead on. All in all, a really great trip, no problems with the van. I did pick up a rock chip on the windshield on my way in to Flagstaff, AZ. I called a local windshield shop in town and they fixed it bright and early the next morning for $35. It took 20 minutes. Beats a flat tire any day. Averaged 27mpg overall, used the factory NAV and Android Auto, again, no issue except Android Auto sucked up all my data on my wimpy 1GB plan. $5 added another gig, so on I went....
Home now, life is good. I love this little scoot.
