The 8-spd with 3.08 diff is better than 6-spd with 3.42 which in prior years was rated for over 9000 pounds. Power will not be a problem. I do highly recommend spending $300 at a trans shop for a higher capacity transmission cooler with either trailer. Get the one your wife likes better and enjoy camping.
Absolutely. People fixate on the tall rear axle ratio and don't realize that an 8 speed with 3.08 gears (4.56 x 3.08= 14.04) will launch better on a hill than an older 4L60E with 4.10 gears (3.06 x 4.10= 12.54) . The shorter (numerically higher) rear axle gears will always launch better given a particular trans, but the newer trans ratios help immensely.
