The block heater is very helpful for the older trucks, and adding the trickle charger was a stroke of genius on the part of OBS solutions and Carrick Customs! The bumper plug mount was easy to install, and it wasn't necessary to remove the front bumper. I recommend other enthusiasts purchase a rivet nut kit (from Harbor Freight or similar) to mount aftermarket accessories into sheet metal. This was my favored method to mount the charger, and it's possible to mount it so that the indicator LED is visible through the front grille when looking from a certain angle. Overall, I feel this kit has improved my ol' truck subtly, but significantly. It's very nice to have the block heater and charger all "nice and neat" instead of messing with dangling cords.
