Best Way To Put SnowPlow In Pickup Truck Bed?

Not sure of your exact situation or capabilities, but it sounds like something heavy.

ME??? I would try to stand it on one end (if I could even lift it). Then back the truck up to it and lay it over into the bed, but keep a chain or strong rope tied down low so the thing doesn't slip down and end up walking away from the truck bed.

Another possibility is - assuming you have tackle and gear or a come-along, use the come-along to lift the end up into the bed, then, slowly working it up, keep repositioning the connection points until you have the whole thing in your truck bed. BE SURE TO TIE IT DOWN EVERY TIME YOU RELEASE THE COME-ALONG OR IT COULD SLIP BACK OUT. Then you're back where you started, with it on the ground, and maybe your tailgate damaged.

Here's a late thought, take your tailgate off first. You might have better luck lifting it up to the bumper first.

Good luck. Hope this helps.

Try to put it diagonally in the bed if possible and strap it down. This will make sure it doesn't slide out of the bed as if you were to put it straight. That's given if you can get it even in the bed in the first place. Unless if you have some sort of hoist that can lift it and put in your bed or if you have a bunch of buddies who can help lift it in, you could try to get it up into one of those tilt trailers and slide it up. Best of luck.

better off putting it on a trailer
