I am probably going to purchase a HD this weekend and i wanted some info on the tonneau. if i dont buy the truck from a ford dealer will i still be able to get the tonneau installed for $250 by my dealer. also it there a lock or "pop" selinoid in the bed already that can be used with keyless entry for the tonneau. if there is will it work with an after market tonneau if i cant get the ford supplied one. thanks for all the healp
