Most of the commercially available options I have seen so far are short on weight limited to about 250lbs.
Let me know what you have constructed in home made or if you have suggestions of the commercially available. I am setting this up on an open span pole building trusses, so I have lots of space to make it stout.

I lift with my back in center to break the seals and then crank up the ratchet straps
I did this on a full size Leer on an F250 longbox
easy

I used 4 ratchet straps and foam floatee noodles on corners

I was looking at ratchet straps, but I need to get it up to the 14 foot trusses to be able to use the rest of the shop. I am doing the same with hoist for the 400lb 5th wheel hitch, so I can do this all myself and don't need 4 people and a tractor.

This looks pretty simple. If you do a rack, you could attach it at 4 points to spread the weight.
Yes, I looked at this format. and I noticed some similar options using a block or a couple of different blocks. Ideally, I would like this to be as smooth as possible, and get it up and out of the way. I am thinking boat trailer winch mounted to the post and pulley directly over head on the truss to pulley over the canopy, but am hoping someone else has input.

They are not designed for that kind of load. Just a friendly warning - I'd hate to have your canopy come crashing down!

Looking around I note this, which is probably cheaper than what I spent.

That's only 65' of rope, but you could modify it to add your own.
My biggest concern with lifting from the bottom is that you are lifting from below the center of mass/gravity, and any slight shift could have the whole thing crashing down. I would look to create a solid attachment to the canopy, somehow (I would try the rack first, I think, low to the ground, to make sure the rack fasteners are solid), and have the lift point from above the canopy. After that, you only need to be concerned about leveling the load so it goes up level.

The guy that built my pole barn said don't use the trusses to suspend things.

Thank you for the heads up.

This one lifts over 400lbs

thank you. That gave me some good ideas. a buddy of mine built one for taking off his jeep tub. He gave me the baseline, and I will take pictures when complete. a little more significant in size, but way low cost with electric hoist. very similar to what you all have suggested in Electric Hoist/winch, but gave me the spanning material and format. more to share in a few weeks.
