Choice between Summit with all available packages and has eLSD, air suspension and active damping or a Summit Reserve with air suspension and active damping but no eLSD. The reserve is $1200 more. I do like the leather in the reserve and the second row ventilated seats are nice too and the upgraded headliner. Hubby likes the tires better on the summit but I like the look of the tires better on the reserve. Will I miss the eLSD if I go with the reserve? We live in Texas so not much snow but do travel to Colorado and North Dakota several times a year. Not much off roading either. Help
