According to the owner's manual for a 2018 Chevrolet Colorado, the negative battery cable must be disconnected to prevent damage to the vehicle while in tow. I cannot speak for what others have and have not done therefore I must recommend you follow the above. If you wish to leave the negative battery cable attached then that is your choice but we cannot recommend you go against what is in your owner's manual. If you do choose to leave the negative battery cable attached then you will risk voiding your warranty if anything were to go wrong.
We offer a product that will allow you to disconnect the negative battery cable with the flick of a switch and for that you will want to use the Roadmaster Automatic Battery Disconnect with Switch for Towed Vehicle w/ Supplemental Braking System part # RM-766. There is also a more cost effective option in the Deka Lead Quick-Disconnect Battery Terminal part # DW05312 but this will require you to open the hood and turn the knob on the terminal each time to disconnect the negative battery cable, you just won't need any tools to do so like you would with the factory terminals.
Unfortunately, the manufacturer does not provide an exact reason as to why the negative battery cable must be disconnected but typically it's so the key can be in the on position to unlock the steering wheel and not drain battery. Please note that if you have a diesel engine in your Chevrolet Colorado then the Roadmaster Automatic Battery Disconnect with Switch for Towed Vehicle w/ Supplemental Braking System cannot be used so the Deka Lead Quick-Disconnect Battery Terminal would be best.
