I'm not sure this is correct. The trailer's tongue weight should be deducted from the truck's Payload. The kerb weight of the Truck includes a full tank of gas.
Mine is working fine. Wished me happy birthday the other day and reminded me that my monster-in-law (sorry mother-in-law) was due to visit on the weekend.
I think it has mostly do do with (a) saving space and (b) allowing the truck to automatically move into Park if you open the door or take your seatbelt off.
I like it because it makes me feel like James Bond.
If you can hold off a few months, I would recommend waiting till the tow assist thingy is available. Not an expensive upgrade but you will appreciate it.
