What's involved in a swap, you ask? Well, mainly dis.
- Unhook -- remove the primary and emergency air brake lines and the electrical.
- Lower the landing gear (ie crank n crank n crank the big jack-in-the-box handle on the side of the trailer).
- Hook the release-latch, plant your foot on your duals (tires) and pulllllllharrrrd while simultaneously yanking to your left so you can lock it in an open position. (It's good that this is hard to do since one relatively little lock around a ball is all that holds trailer and truck together.)
- Get in the truck and carefulcarefulcareful pull out, watching that the landing gear holds before completely pulling out from under.
- Hook Up. Back under the other trailer until THUNK, the plates meet and the latch closes around the ball.
- Try to pull forward (with the trailer brake on). If you can't, you're connected.
- Hook up the air and electrical.
- Lift the landing gear (ie crank n crank n crank, only dis time the other direction)
- Feel the burn! Wipe the brow! Screw the gym membership! woo hoo!
