Old New Couple to Alaska

    Hello,
    We're a couple 83 years old with a yen to drive the Alaska Highway again after first doing so in 1955. This time we'd use the Cassiar Highway as part of the trip. Has anyone done this or anything similar? We have a 1999 Chev Suburban K1500, 5.7 engine, with 160,000 mostly commuter/highway miles by the first owner. We have proper equalizer hitch and sway bar and would pull a Holiday Aluma Lite trailer, 23 feet long, weight about 4,500 pounds loaded.
    Where do I find my rear gear ratio?
    Thanks much.
    Jesse Thompson
