On my trip last week I drove my Tahoe around for the week once I got to the destination in Sedona.

When I went to depart on Saturday the Tahoe battery did not have enough power to pump up and maintain my brake buddy.

This is the first time this has happened.
I have 2 brake buddies, a primary and a spare and both said no go.

So I figured I need a new battery.

I was thinking I should get more of a deep cycle so it would last during my trips of 6 to 8 hours. Or go back to harbor freight and get the cheap solar panel to charge the battery while going down the road.

Anyone tried a different type of battery for this application ?

Thanks for the feedback.

Can I assume there is no 12v charge line connected from the motorhome to the toad. That will keep any battery charged while driving the rv.

I'd go ahead and get whatever starting battery your vehicle requires. Then, wire in a 12V charge line from your Motorhome to the Tahoe so this won't be a problem anymore with the new battery.

That way, you won't be using your vehicle's starting battery like a deep cycle battery, and ultimately shortening its lifespan as a result. Cars really need a starting battery, not a deep cycle. If you use a starting battery like a deep cycle and deplete it low regularly....Welll, you shorten its lifespan and end up in the spot you're in now.

Find a way to run a charge line to your Tahoe, is my vote.

If your Towed is in the key OFF position why would the battery discharge ?

Just food for thought...we use a Brake Buddy and tow 5-6 days without starting the Jeep. In the 4 years we have been doing this, we have not had any battery issues. I suspect replacing the Tahoe battery will resolve your issue.
And yes, a charge line will certainly eliminate future problems.

This depends on how many time the brake system is deployed every day If in city you my be using it a great deal using up battery more then you think. Get a charging line be safe.

If you drove your toad for a week and the battery went dead, you might want to have the alternator checked.
