Same here. I was looking at a few in the $200 range, but they all seem like internal ones. I will need to mount mine outside. They look super easy to install but have not had one priced out by an electrician yet.
I have been doing the same thing! I figured I would use the 7.2 every now and then, but this sold it for me. Luckily the blower on the furnace only uses 400w. Been running for days with no issues. I only wish I could turn the screen on the dash off.
I really like the column shifter. It gives me a bit more room in the center console to store junk. I forgot to shift to park when I shut off the truck the other day and found out it will shift it into park on its own using a motor.
