i have the viper 5901 on my F-150 DD and love it, to my understanding but i could be wrong that clifford and viper are basically the same thing.

This thing has alot of options, add ons, and features i still havnt figured it all out yet and its been on the truck for 6 months lol ( just learned what i needed to ) there is still a lot more this thing can do i just need to read in my owners manual i guess lol
