What about putting the saw in the bed on it's back spine? This would require tilting it down ONTO the tailgate and then lifting it up and sliding it in. This would put about half the weight of the saw on the tailgate. It's a 650lb saw. Tailgate wont close as the saw is 84".

I need tires but can get those tomorrow.

I remember hauling my 400lb motobike no problem and another time I hauled about 500lb in wood, might have been more. Tires def were compressed some. Seemed to sag too. It's on the orig leaf springs and probably 20 year old shocks.

For $70 I can rent a full size crew crab from Budget with unlimited miles. THis would allow my wife and dad to come, maybe even my nephew. Might do that.

From my research and talking to Laguna, they recommend truck hauling on the back instead of vertical. Pic of saw below.
