I was somewhere around mile 280 of a late-October push through the Oregon high desert when I realized my Strada’s lead-acid battery was genuinely done.

You’ll hear two completely different stories about lithium upgrades on a Roadtrek Zion. Dealer service departments will tell you the stock charger and solar controller are fine, that you’re better off sticking with lead-acid because it’s “simpler,” and that any custom electrical work voids your warranty.

I opened the battery compartment on a Thor Sequence I’d picked up at auction and caught a whiff of something sharp—not quite burned plastic, not quite sulfur. The moment my eyes adjusted to the dim light and I saw the crusty white corrosion climbing up those lead-acid terminals, I knew exactly what had happened: the … Read more

Right now, my Airstream Rangeline is parked in front of me, and I’m staring at the cramped battery box nestled under the wet bay. It’s a tight fit—barely large enough for what Airstream managed to cram in there from the factory. When you pop that lid on any stock Rangeline, you’re met with a single … Read more

Hey there, I’m Drew Callahan. After traveling over 80,000 miles across North America in three different rigs, I’ve seen my fair share of RV setups, and one thing stands out: if you skip the battery management system setup on your Jayco Terrain lithium install, you’re not just leaving charging capacity on the table.

I’m Drew Callahan, and after traveling over 80,000 miles across North America in three different rigs, I’ve seen my fair share of issues with RV air conditioning systems.
