Don't let all the stuff I said convince you to not get the trailer - sounds like you were looking forward to it. I think the Frontier will be OK if your truck is set up right with a WDH and sway bars. The hitches aren't that hard to set up, it's usually the weight that makes them cumbersome. The Andersen appears to be much lighter which would help with the hooking up/setting up. I think some on here have one and maybe they will chime in on the ease, or lack, of installing one and how well they work. Another thought would be to have the dealer where you buy the trailer install it - many do. My concern is getting the hitch. You will need the sway control to keep you safe IMO. (And check those weights on the sticker inside the door).
One thing on installing one; do you have the tools to install it? It will take a torque wrench, sockets etc. If like mine, it takes a torque wrench that exceeds 300 ft. lb. and a large, thin walled socket for the ball.
