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.

It was a tough decision but I did go with the Andersen. Had my GM dealer install a turnover ball (could not muster courage to take a hole saw to the box) but I installed the Andersen. EZ install. Photos attached.

The Andersen hitch weighs 35lb, compared to the B&W slider also under consideration at near 300lb. Also saved some weight by purchasing a Lion Energy lithium battery that weighs less than 21lb in lieu of two Interstate 27C's.

I live in Montana and will be locating the new trailer on a small lot we own that is around 7,000 in elevation. As of last Friday there was still 4' of snow in the yard. Plan to pick the trailer up on Wednesday, May 13 assuming no snow this weekend.

Truck is a 2017 GMC HD3500 SRW with a 17,200lb tow rating and a 3,927lb payload. Trailer is a 2020 Grand Design 2930RL with a dry weight of 11,442lb, GVWR of 15,000lb, and a hitch weight of 2,174lb. I think I am well within specs but the DRW guys still have me double checking numbers.

Will let you know how well it handles and turns after my first run.

Nice, thanks for the update. Does your truck have any lift in it?

I have a level kit and 2 inch blocks it shouldn't be a problem but I know people with 4 inch lift or more can have a problem with 5th Wheel Towing. Also are you aware of the recommended brackets by Andersen for the GM models we are driving. I know it applies to the 2500 not sure if it applies to the 3500. Andersen part 3243. They are supposed to stiffen the bed floor and cost $90 for the pair of brackets.

Lifts can change the geometry of a truck and a hitch. Mine is not lifted so I can't comment. Am aware of the Andersen supports but have not read any reviews where people are using them...and have not read any reviews where Andersen hitches have warped beds. Of the few failures, most seem to be the hitch itself collapsing. Your question is exactly why I requested advice from the forum. Hope I don't send you a photo of my warped truck bed, but I will post comments, good or bad, after some use.

Sorry if I am late to the party. I've had the Anderson Ultimate for going on 4 years and over 20K miles towing (almost 3K lbs pin and 16K lbs total).
No problem with the bed warping (as of yet), but I am torquing the bolt down to 60 ft/lbs because the hitch (after 1,000 mi or so) has a tendency to rotate CCW just a little bit.
Did not know about the brackets 'til NHfireDmax mentioned them.
Happy with the hitch so far.

Bought my new camper, and ordered the BW kingpin and Anderson Ultimate (toolbox version) and the stiffeners (extra $80, why not) Probably not needed but also some 5K airbags. Pin weight is only 1300# its a 29' 5th. I have a compressor already for the truck...
