Eh, I’ve used dewalt tools almost daily for the past 5 years and rarely had a battery go bad, but sounds like you’ve got a handle on it with the service truck.
As for what I’ve been doing, we’ve had crap weather the last while so it’s been a bit since I’ve driven the Duster. As far as the valiant goes… you may have missed it but we sold the farm and moved 18 months ago. We down sized to 4 acres with no shop, so my car projects have all been on hold until I get my shop built.
I’m doing a YouTube shop build series if you’d like to follow along.
