Okay, I went ahead and decided to try this. It went really well, and I like the mix of modern and old-school on my 1967
For those wanting to do this, here is the parts list:
1ea Renogy 100W Flexible Solar Array $220
1ea 46" x 21.5" x 0.1" plexiglass sheet $ 33
6 ea Stainless 10-24 x 1" bolts, washers, nuts $ 10
1ea Windy City P30L LCD PWM Charge Controller $55
25ft MC4 10ga Battery Cable $40
23ea 3/16 aluminum rivets and backing plates $ 8
1 tube Clear silicon $ 8
I went with the flexible solar panel to save weight. You could probably use a standard solar panel, but I was concerned with the weight. The flexible panels weighs about 5lbs. A standard panel weighs about 25-30.
The frame for the rock guard is 46x24" outside dimensions, 44 x 22 inside. The solar panel is about 41 x 21. I could not find any solar panels that would be a better fit than this.
There you have it. It took about 3 hours start to finish to remove the old panel and install the solar panel on the front of the trailer. I have not finished wiring the panel into the battery yet, it's too dang hot outside to do that now, I'll wait until later on tonite!
I hope this is useful.
