These Gen 3 Sliders are WAY easier to install than Gen 1's & 2's seen on videos. Almost paid good money to install; but, I'm super glad I didn't. If I had a video to watch, I could've done it in half a day; but, because of researching, and even instructions giving me Gen 1 directions, I had to stop and wait for tech support, for the on/off switch wiring instructions. If I had to do it again, I can probably get them installed in 3 hours. A ding on the 4WP website.... 4WP doesn't offer the armor; which, I had to order directly from manufacturer. Cost extra; but, when I hit the Rubicon next year, it will have been worth it. With armor install, I think it would take about 9 hours to get done. Otherwise, super easy for the mall crawler install without armor.
