I have a solution for you, but first let me show you how to determine if the B&W Companion Slider # BWRVK3400-5W will have enough clearance for your soon to be new toy hauler using our clearance formula.

Below is the Clearance Formula that we use to ensure there will be enough space between your truck cab and trailer when executing a 90-degree turn. NOTE: At least 4 inches of clearance is recommended to safely execute a 90 degree turn.

(36 + 12) - 51 = Clearance = (-3)
36 = Distance from center of fifth wheel hitch jaw to truck cab
12 = Offset used (slider clearance or Sidewinder offset)
51 = Width of trailer divided by 2 (to get half)

As you can see the Companion will not give you enough clearance to make a 90 degree turn with your Sierra. Since you haven't purchased the new toy hauler yet you have a few options. One would be to attempt to find a narrower trailer, which aren't common, to get 90 turn clearance the trailer would have to be no wider than 88 inches total. Second would be to upgrade your towing setup to accommodate the 102 inch wide toy hauler you have your eye on.

Since the Companion is the absolute best option for your gooseneck setup, upgrading would be to remove the gooseneck and put in a 5th wheel setup. For an above bed setup you will want the 13K # DM8550040 and rails # DM8552011-71.

If your new toy hauler is over 13K you will instead need to install a standard hitch like the 16K # RP30047, the above bed rails like # RP50066-58, and the Sidewinder that matches your trailer's pin box, see helpful link, as well as the correct wedge, for this 16K 5th wheel it is the # SWW-03. If you would prefer an under bed system, I recommend the # RP30868 with the 18K # RP30921 and # RP44FR wedge.

I have linked all of the above mentioned products to this page as well as all the Sidewinders and a few installation videos for your viewing and purchasing convenience.
