I have probably 4-5000 miles using the goosebox now with perhaps 2 dozen hookups.
Towing it seems ok, as mentioned before, different from what I had, not better or worse, just different.
The trailer sits a bit lower on the truck. Enough so that even with cutting the "ears" on the pinbox frame I still hit my roll top cover bed rails on uneven ground. I cannot use the air bag to gain enough height to clear the rails on tight uneven turns.
Hooking up is a royal pain. Based on just the difficulty of dropping the hitch on the ball I would NOT RECOMMEND this hitch to anyone.
The hitch needs to be about perfectly centered over the ball to drop. The cone on the hitch is the reverse of what it needs to be. If you look at the Anderson hitch they now have a polymer cone that will allow the ball to not be centered. Drop the hitch off centered and the cone will guide the ball up into the hitch.
Dropping the hitch onto a not centered ball just allows the hitch to sit on the top of the ball. Even if the reverse cone is a bit over the downslope side of the ball, the friction will not allow it slide over and down. That might be amplified by my front jacks being angled out, which minimizes side to side movement.
Probably got spoiled with the jaws of a conventional hitch having a wide receiver for the pin along with a MOR/ryde pinbox allowing 3" of total side to side movement of the pin.
On flat level ground it may take 5-10 minutes or so.
On uneven ground I have spent probably 30 minutes hooking up.
I have added blue tape stripes to the goosebox and my toolbox. That helps a bit.
I have given up using my portable backup camera. It helps some, but it does not have image reversing capability, so using mirrors and non reversed image is a challenge.
I do use a magnetic pickup tool to at least tell when I am nearly overtop the ball.
Disappointed with:
The first hitch delivery (damaged boxed with hitch not in the box rolling around, damaged, parts missing)
The 2nd hitch air leak, misaligned parts allowing scraping and squeaks, useless correct air pressure decal
Difficultly hooking up
You still need to keep a good amount of clearance around the ball because of the shape of the goosebox
Disconnect height required (have to get in the habit of always using my 2-by pads under the jacks)
Lack of response from the Reese Goosebox people with regards to the reverse cone shape.
Before dropping the hitch on the ball but directly over it, there is only about 2" of clearance between the open tailgate and the RV. That doesn't leave a lot of room for error when not backing in perfectly straight.
Have I mentioned how hard it is to connect?
Pros - empty bed with 10 pound ball removed.
