Most of the new trailers are built so that you don't need a slider hitch to pull with a short (actually now called regular) bed truck.
I the edges of the trailer are angled, you almost certainly won't need one.
If you do need one, I would also suggest an auto slide. They are more expensive, and much heavier than a standard hitch, but it is nice to not have to worry about stopping, and sliding the hitch. I went from a Reese manual slide to a Superglide when I needed a slider. And I wouldn't ever go back to a manual slide.
If you don't need a slider, I would look at a Reese Elite series. I borrowed a truck wth the B&W once, and I prefer the Reese. Smaller, lighter weight, and seemed easier to latch while still not having the risk of high hitching.
