Go with a 12-14K hoist, minimum. 10K is barely enough to lift the truck stock, and a 14K will have enough headroom that it will feel solid when in the air. I work on this stuff every day and even my 14K hoist feels a little dodgy with a CCLB F350 up in the air. I trust it, and I work under it, but it rocks enough doing any heavy work that I use the 4-post with center jacks for front end work, or anything more than oil changes and tire rotations.
Bendpak is good, Rotary is best. Don't cheap out. You're not lifting a 2800lb Miata with it. I've been around hoist failures and it's not a fun experience.
To be perfectly honest, the best/safest way to lift a vehicle that big is a 4-post with center jacks. Again, go with a 14-15K, so your rear center jack will have enough capacity to lift the rear of the truck.
