FYI Battery Booster

[Joe Hogan]

Recently we arrived at a campground with the Towed having a low battery. On newer vehicles if the battery is too low the starter circuit is disabled.
Luckily, being the ever paranoid guy, I carry a battery booster, Amazon.com .
Pulled out the booster and the vehicle started.

These items are relatively cheap and great to have when needed.

I carry the same one in my toad. Good choice.

Maybe check that your coach is powering your toad while towing? I use blue ox and had to make sure I had the pins setup properly so the battery is being charged while towed.

What's causing the drain for just a few hours of driving though? With an average of 4-6 hours for a RV trip, what would cause a significant discharge?

When I bought my 2017 GMC Canyon, they gave me this charger.

The most goodies I ever got with a new vehicle were a pen, a tote bag, and a mug.

I, also, carry a Noco booster pack. Ya never know!

Another positive for this charger, I've had it since 2017 its never been charged except for the initial charge. I had to use it a few weeks ago on my lawn tractor and it was still showing full charge.

The NOCO can be charged using a USB outlet. Simple to use and holds a charge.
The reason the battery was low is still a mystery.
The battery needs to be disconnected during the Flex tow. We use a disconnect solenoid on the main battery terminal.
