We ordered a Grand Design 2930rl fifth wheel and expect delivery in mid-March. We have owned several bumper pull trailers but this is our first fifth wheel. My tow rig is a 2017 GMC HD3500 Duramax with a 6.5 foot box. GVWR and hitch weight appear well within specifications.

I am interested in an Andersen Ultimate Hitch for the reasons of weight and ease of removal, but have not bought the hitch yet so I can still go another direction such as a Companion Slider. I have a B&W turnover ball. Without a hitch or the trailer, I cannot perform any measurements so I am going off internet reviews, which may or may not be reliable. 'dunno;

I have reviewed the Andersen installation instructions and would appreciate insight from list members who have installed the Andersen Ultimate in their short box GM. Did you install the coupler block ball socket to the front of the kingpin (toward the cab), or behind the kingpin (toward the tailgate).

Can you comment on your turning radius? Any problems or concerns?

Have you had any clearance problems with siderails? Does anyone have a tonneau cover? I am expecting to remove my Extang Encore three piece hard folding, but might it still work?

Finally, does anyone have any nuggets of wisdom for a fifth wheel newby regarding my setup?

Any responses will be greatly appreciated. Thanks.:smile2:

I have the Andersen for my setup. It was first installed in te 2017 I had, and yes, the coupler was turned to the back. I have changed vehicles to a 2020, and it it is still turned to the back. As for turning radius, I have no issues. In the 17, I first had it mounted in the front, but would hit the side of the bed.

I also later raised the pin, so that may have helped the situation instead of turning it around. I am going to turn it around on the next trip to see how it works.

I love the hitch. Hangs on the wall in the garage when I don't need it in the truck.

I have had an Andersen for three years now with my 6.5 foot bed, No complaints, would not use any other set up.

My adapter is set up so the pin is in front of the ball. Works great, I can easily turn 90 degrees (did it once in a paring lot just to see) without hitting.

I store mine in the front garage of my camper when not in use. My 12 YO takes it in and out for me.

I am pulling a Jayco 355 MBQS.

Also easy to unhook and hook up.

Thanks very much for the reply. Greatly appreciate your insight. A few questions if you have time.

For my our clarity, I assume you are set up with the Andersen coupler ball socket to the front of the trailer's king pin. If that is correct, do you have any problems with the hitch making contact with the bed rails? What pin setting to you have the Andersen ball set on? Bottom (lowest), middle, or top (highest), and do these height settings have much impact on bed clearance or turning radius?

I have the coupler the other way. The ball connects behind the pin on the hitch. As far as the height settings, the camper is in storage with the hitch, so I don't recall. But no I do not have any issues with the hitch hitting the bed in any way. And I have about 6 inches of clearance between the top of the bed and the camper. Like i said, it has been great.

Any other questions, let me know.

Again, thanks much for the reply. Our investment in the truck and RV is sufficient enough to generate some hitch anxiety. Appreciate advice from an actual user.

Can someone give me the kingpin dimension in the bed front to rear? Trying to see if the Andersen ultimate hitch TBX (tool box model) will work with my tool box and headache rack...

THANKS
EDIT: found 44.75 on line... Looks like I'll have about an 1-2" to spare...

Might want to spend your dollars on something other than Anderson. Although a great product they owner of the company is not so great. Although he admitted his faults so that’s a start.

Dumb move by him, no doubt, but that does not change his product. It was a one-time isolated event. If he was a repeat offender I certainly would not support his product line.
