I just finished installing the Schrockworks sliders on my '14 TEP. Wasn't that bad, took me about 2 hours total, working by myself.
Gotta' say the tips and tricks posted here helped a ton, as I knew what to expect.
After reading about all the potential issues when you remove the strap for the gas tank, I ran my fuel down as recommended until the light came up (ended up still having 4 gallons in the tank). Then I placed a socket on top of my floor jack, and gently inserted it into the hole in the skid plate right next to the strap you're removing. I only lifted it enough to contact the gas tank. That way when I removed the strap I had effectively pinned the tank into position, so the strap didn't move.
Sorry the pix don't line up with the text, it's my first post with pix and I don't know how to attach them at a specific point.
Couple of things that will help you on the install - use the box they ship the sliders in to support them during the install. I added a couple of 2x4's on each end and it positioned the sliders almost perfectly (meaning the holes lined up nicely)!
I used the trick posted earlier and used some shims to push the KDSS lines away from the frame, that allowed the slider to slide right in behind them against the frame.
Really wasn't as bad as I expected. Turned out nice, I'm very happy with these.
