taking my top off...one or two straps?

When I had my fiberglass cap on my old pickup, I used a stand that I built.

I parked the truck where I want the cap, I then sunk 1 4x4 at each corner (in a few inches front and rear) of the cap, then ran a 2x4 along each side of the vehicle. Then I cut 2 more 2x4's to go across the other 2. I would get inside the bed, lift up a couple inches on the cap with my back and slide the 2x4 cross ways along the front and back.

Drive out from under it.

To put back on, reverse process. Seemed to work quite well.

that would be the easiest way
only problem is,
the truck has a full size roll bar in it, so i cant do that, or id catch the bar

As a kid I had a train setup on a 4x8 sheet of plywood suspended ironically above my dads 67 Dart. We used one rope for each corner. The 4 ropes come to 4 pullus that followed down a post in the garage. Never had an issue having the thing go up and down flat. I have a bicycle lift (harbor freight special) it uses one rope and sometimes the front goes up first and sometimes the rear.

I would go for the multiple rope setup!
i thought of buying 2 of those bike lifts and call it good, but i would be right at the max weight
