I'm looking to get some AMP Research running boards soon. I live in Oklahoma where we tend to get more ice than snow (about 4-8" per year). I'm currently debating the standard Powerstep vs Powerstep Xtreme (NOT XL). The Xtreme model comes with 4 motors compared to the standard 2 and has a 2-3" wider step from what I understand. Both kits come with a 5 YR-60,000 Mile Warranty. I know the snow won't be an issue whether in state or on a trip. But for an extra $350 does anyone see a benefit of the Xtreme 4 motor system lasting longer? These steps aren't cheap and I'd like them to last as long as possible. Any personal experience and/or opinions are welcomed, thanks!
