Ladder Rack for 2019 GMC Sierra 2500 that Can Fit with BAK Tonneau and Carry Bike Rack

Question:

Is this Thule rack the only one that would work with this? Or would any roof rack work? Second question - I noticed the Thule rack has a max crossbar spread of 43". My stake pockets are much further apart than that. Does the Adarac ladder rack let you change the spread of the racks so that I could bring them to 43" apart? Or is it in a fixed position? I also just want to verify the ladder rack you sent me is the correct one for a folding tonneau cover. You sent this one, which has the supports curved in a bit A4001232. I was under the impression I would need one with straight supports like this - A4000966. Maybe that's only for the tri-folds though? Mine is a quad-fold. I definitely prefer the look of the one you sent, so if that will for sure work that's great. One last thing... is there any kind of system that could work where the bike would sit down in between the ladder racks, and on top of the tonneau cover? I haven't seen anything like that before, just thought it would be worth asking because that would keep the overall height of my vehicle down. Sorry for all the questions! I travel full-time in an RV and have really limited access to mail and have an opportunity to have it shipped to a location this month, so I want to make sure I get this right!

Adarac does offer a ladder rack that fits your 2019 GMC Sierra 2500 that has top channels you could mount a bike rack into with the Adarac Aluminum Series Ladder Rack # A4001232 that also will fit with your Bakflip tonneau as well.

Then for a bike rack that can fit the top channels of the load bars the Thule UpRide Roof Bike Rack # TH599000 would be a great option that allows you to leave the front wheel of the bike installed as well.

Ladder rack bar spreads tend to be pretty far apart since they usually install at the front and rear of truck beds. Most roof bike racks are designed for a much narrower spread since roof racks typically have a much smaller spread between bars. I actually think your best option currently is to go with a roof rack on your Sierra like the Thule # TH711520, # TH710501, and # TH145105 to carry a bike rack. To do a lower sitting ladder rack for your truck bed would require replacing your current tonneau with a retracting Retrax XR like # RTT-80462 so that you could install a Yakima Mid Height Truck Rack part numbers # Y01152-5655. This would allow you to have the bars closer together for roof rack accessories to fit and would give you the lower height you want as well.
