I work in a RV and Fab shop in Lynnwood,WA. I was installing a Banks system on a 41' diesel pusher motorhome and due to circumstances beyond my control (wrong parts) couldn't finish the job before closing. This was a problem because the doors on the shop would not close would not close (40' shop.) I pulled the coach off the lift with a strap in 2LO no problem. The next morning I pulled my K5 up to the other side of the shop (has drive through access) and reeled out the cable. Using the hoist as wheel chocks, I single-lined it to the ramps. Then broke out the snatch block and double lined it up the ramps which are about 10" high (remember this is about 18,000 lb of coach.) The nose of my truck dropped about 4" when those tires started up the ramp and the winch started goaning a little, but it pulled it up onto the lift no problem. After that incident, I don't think any thing I encounter on the trail will phase it.
