Can I Leave Battery Connected on 2014 F-150 FWD While Flat Towing

Question:

After the transfer case has been placed in the neutral flat tow mode, the manual says the battery has to stay connected. Is that true or can I install a battery disconnect?

The vehicle owner's manual is always the best source of information on the procedures for flat towing a vehicle, so yes, you will want to keep the battery connected. If the concern is that the battery might be drained during flat towing, I recommend installing a charge line kit that will keep your battery from being drained during transit.

For the vehicle side you'll want to use the Roadmaster Battery Charge Line Kit for Towed Vehicles # RM-156-25 and if there is not a charge line present on your RV you'll want to use the Roadmaster Battery Charge Line Kit for Motorhomes # RM-156-75.

I've linked some installation videos of these parts for you to have a look at.
