I'd be nervous, and approach your choice really, really carefully. I'd be all over YouTube seeing what people commonly do, and hopefully some people here have more experience to add.
My experience so far with ramps has been into a U-Haul box truck, and into a small enclosed utility trailer. Both are lower than a truck bed. What year truck? How high up is the bottom of the bed? Newer trucks are being built so high these days it's getting crazy.
Ten foot ramp means you'll only have about one foot in front and back with the bike centered. With today's trucks that sounds fairly steep to me. I'm sure it's doable but could be hairy and not something I'd want to repeat very often.
How wide are the ramps you're looking at? Wide enough to have your feet down? How much help will you have getting it in and out? I always have at least one other person. On the slightly taller U-Haul I got two guys to help, and it was still a little sketchy because the ramp wasn't very wide. Sometimes you only get one shot at getting it up or down. There's not much room for error, because the bike is too heavy to man handle if things start heading south.
What's the weight capacity? I've used an 800 pound rated ramp into the utility trailer and it bent a little.
Glad you asked this. I'm really interested in reading other replies.
PS… Almost forgot, I have one other experience with ramps. When my bike was shipped to Italy, it was delivered to the navy base on a small truck. The Italian movers opened the crate, but had no ramp with them, and probably had never seen a bike that big in their lives. They literally looked around, saw a construction site across the street, walked over and borrowed a 2x12 and half a dozen guys. Watching the bike come down, the board deflecting at least a foot under the weight, eight Italian guys giving it everything they had to get it down… all I kept thinking as I watched was… I've got insurance. I've got insurance. I've got insurance.
So yeah, ramps still strike a bit of fear into me…
