Aggie61, the Outfitter was new to me, wasn't aware Boonedox had this. I have the T-Bone extender and it is a quality piece and I am sure this device is, too.
Like Tallgrass05 said, it's pretty pricey. Two or three pieces of really heavy nylon straps, say of the 4 to 6" wide kind, that stretch side to side on a truck bed would be a light and form a sling.
Hard to say how much time and effort, though.
All of your options look good to me. I'd pass on a trailer, that being my last choice if all else fails.
