Mark, you may actually be right!
But I'm willing to find out for myself.
I'm fairly optimistic because I can use a substrate to actually lengthen the bed a bit if I only need a few more inches to accommodate the Shark cage.
With my F150, I had the 5.5' bed as well.
With the tailgate down, you gain the extra length you need for the Tenere (and my brothers Vstrom)
As I stated earlier, I take a sheet of plywood and mount the chocks to it. Then slide the plywood into the bed.
Since the sheet is much longer than the bed and extends over the tailgate, it helps strengthen the tailgate.
I even cut it to length allowing it to extend a few inches beyond the tailgate. That allows me to drill holes through the plywood overhang to line up with holes in the ramp lip.
I insert lockpins into the holes so the ramp doesn't slip off while riding up it.
I use the same holes\pins for storing the ramp while traveling.
Hoping I can just start over with the Dodge 2500 and possibly come up with a bed\ramp rig that works with the Shark Cage.
The loooooong ramp will be a luxury for me.
Here is the previous setup. And yea, that poor little half ton needed airbags for those 2 pigs and our wives in the back seat.
By the way, ALL of this effort was the fault of eemsreno. He cost me $airline tickets, airbags, and 3 more weeks of vacation.
(long story, but I'll never be able to thank him enough!)
