I have the Supplimental Cab Heater in my 08 Ford, I would recommend it highly. Its not a rear heater it justs puts out alot more than the regular heater, and its easier to do that now than later.

Also If your thinking of the other options, I would and would not get again.
NOT- Backup sensors - Screw up alot in the winter, pain in the butt.
NOT- Traction Control - Useless option

DO- Navigation System - Awsome
DO- Dual Alternators - Good when you have a trailer
DO- Rear Stableizers - A cheap option
DO- Rear tailgate step - Awsome
DO- Trailer towing mirrors and trailer brake pkg - Awsome
DO- Rear box extenders - Cheap option and handy

Here is my option list not all are on here as they include some of them in different packages
