Parts Needed To Install Demco Autoslide 18K 5TH Wheel Hitch On 2019 GMC Sierra 2500 With UMS  


I have a 2019 Denali 2500 6 ft bed. I want to mount a Demco 18K fifth wheel hitch model 6003, MFG 10/20 with side brackets for rails over the bed. I want to buy the underbed mount puck frame rails and bracket. DM6004 and DM8551010. Does this look like the correct part numbers? thanks


Helpful Expert Reply:

Yes, you do have the correct part numbers. For your Demco Autoslide 5th Wheel Trailer Hitch # DM8550034 the Side Plates # DM6003 are the part number 6003 you referenced. To mount on the Underbed Rail and Installation Kit # DM8551010 for your 2019 GMC Sierra 2500 you will need the Side Plates # DM6004.
