Hi Michael!

I can definitely get you everything you need to set up your 2020 GMC Yukon XL Denali for flat towing. I have a list of everything below:

Blue Ox Base Plate Kit - Removable Arms # BX1718
Blue Ox Avail Non-Binding Tow Bar - RV Mount - 2" Hitch - 10,000 lbs # BX7420
Roadmaster 4-Diode Universal Wiring Kit for Towed Vehicles - 7-Way to 6-Way Coiled Adapter Cord # RM-15267
Roadmaster Battery Disconnect for Towed Vehicle w/ Flat Tow Brake System - Gas Only # RM-766
12 Volt Outlet Kit, 20 amps # RM-9332
Blue Ox Patriot Portable Flat Tow Brake System - Proportional # BLU37TR

I know all of this is not Blue Ox, but Roadmaster makes better wiring/electrical components than basically everyone. All the other parts (base plate, tow bar, and braking system) are Blue Ox. Oh and the tow bar includes safety cables, so no need to get extra ones.

What kind of RV will you be towing this with? You mentioned it being a Class A diesel pusher, but I don't see people pulling full size SUVs like this very often and am curious.

Thank you for the information. Do you need to disconnect the driveshafts with this set up? If yes, is there a quick connect/disconnect option? It is a 2008 Monaco Executive with the Cummins ISX 15 525HP. I would love to tow something smaller, but 2 Great Danes, 3 Kids and 2 adults just dont fit in a Kia! If there is a better set up I should consider, please let me know.

@MichaelN That's a nice RV! Always liked the Monaco rigs. You will not need to disconnect the driveshafts when towing. There is a section in your owners manual that will go over what you need to do. It's a little bit of a process, but once you do it once or twice it will be totally natural. One possible thing I would change is the braking system. The Blue Ox Patriot is very nice, but I will admit to preferring permanent systems. And since your Monaco has a diesel, you do have air brakes. The Demco Air Force One Flat Tow Brake System for RVs w/ Air Brakes - Proportional # SM99243 is one of the best on the market and is actually a little less expensive at the moment. And I hear you about needing a big vehicle. I'm 6'5" and am resigned to the fact that I will probably never have a vehicle that gets awesome gas milage. But on the flip side, big cars are more comfortable. Win some and lose some, I guess! : P
