From experience, I can tell you that the Demco brand base plate is the cleanest, easiest installation of them all, and also incredibly stable and sway-free when flat towing.
If anyone needs the Deco base plate for a 20–24 Maverick I’ve got one that I used once (from Atlanta to Orlando and back)...
I remain convinced that it is absolutely the best way to go for 20–24 Maverick. It is the easiest/ cleanest Insulation of all of the brands.
Unfortunately, the early style baseplate doesn’t fit my new 2025 Maverick.
So, I have the complete base plate kit available for sale for 2020-2024...
