I looked into it, and Silfab is really one of the best solar panel brands in the world. Excellent for my purposes, competitively priced, and expanding when other businesses are contracting. Btw, all black panels look awesome!

My solar panels have been up and running for 8 days as of this review. Someone I trust strongly suggested them, so I went with it. The installation process and obtaining the necessary municipal permissions was the part I was most afraid of. But my installer did all the work and it was a breeze.

Is this a panel suitable for an rv trailer solar off grid system with battery backup? Please explain and if yes ...can you offer a DIY design yo utilize you panel?

This panel should fit on the roof of most RVs. It's also a good choice for an off-grid system. We do not provide instructions per se, but we have written a number of DIY articles. Click "Magazine" at the very top of our website. We have an entire compilation dedicated to solar for RV
For two 380 watt panels wired such that having a total of 760 watts, what amp size charge controller would I need.

The wattage of the panels is only one of the parameters to consider when sizing a charge controller. The second is the voltage of your battery bank. To arrive at the optimal amperage, just divide the total watts of your array by the voltage of the battery.
How much is shipping to florida.?

Shipping starts at $250 for up to 8 solar panels, and goes up by $25 with every 4 modules on top of that. Some panels qualify for free shipping when ordering over 10 items.
