Recommend a good solar trickle charger...

[Blueswede]

I'm looking to pick up a good solar charger to keep my batteries charged when my trailer is parked where we store it. Lots of sunshine here in So Cal. Just don't want my batteries going dead. Thanks.....

I bought one at Tractor Supply for my car hauler battery (winch). I've also seen them at Walmart and auto parts stores. It's approx 6"x18". Can't recall the output, but you don't need much to maintain a charge.
