Oh yeah that makes sense, maybe he's just using regular tie-downs.
It still sounds odd, you wouldn't gain any clearance, the lift still goes under the truck in the same place. And you'd lose a big part of the convenience of a SL, automatic tie-down.
I've always questioned the angle of most rear tiedowns that reach toward the rear... they put rearward tension on the camper which actually helps it slide backwards out of the bed. That seems wrong to me. Sure they help keep it from sliding forward, but so what, it's got nowhere to go forward, it can only slide backwards.
I've always set my rear ties to be straight down. I've had issues with campers sliding backward before, taking off from a stop on a steep hill. Real spooky when an 11.5 does that on a regular-cab truck on a steep hill, I thought I was gonna do a wheelie and drop the camper right out like a dump truck.
