Scotty is guarantee for as long as you own it. That is what swayed me to buy Scotty over Cannon. Have not had any problems with it since it was new. (4 years) Fast retrieve, no power needed to lower.
I don't think the depth counter is very accurate. I let out 30' of cable, but my tape measure showed only 24'.
You will get several answers, but it will come down to a Ford or Chevy. Good luck.
