Not sure how rounded the corners on your front cap is on the Wolfpack but my uncle has a B&W non slider companion that goes into the puck mount on his 2015 mega cab short bed. He tows a 2008 Montana and likes the hitch a lot.
Another buddy has the Anderson with his short bed GMC 2500 towing a Voltage. He likes his Anderson a lot.
I have the B&W companion that fits in where the gooseneck ball goes on a 2015 Ram dually longbed. I like this hitch a lot.
My buddies Anderson is definitely lighter and easier to take out of the bed then my companion, but the companion is easy to take out also by one person if you take the head off the base when removing which is pretty easy. I like the companion better because it looked a lot more heavy duty then the Anderson. It was going to be between the Anderson or companion as I did not want rails in my bed anymore.
I've had slider hitches in the past and don't miss having to get someone to help take it out or break out my engine hoist to get it out of the bed.
