Do they instill solar units?

No, but they install them.

yes, if purchased through them.

I would look for a place that specializes in installing solar panels. I don't think i would trust a dealership be to fo it.

Curtis Trailers will not let you go to their repair building for a reason! I would not go there for repair, we gave them three chances to get it right and it got worse! I would not go to their shop.

I fully agree with the previous answer

Most "New" Trailers come with a "Solar ready plug" where you simply plug in a portable panel... However IF you are installing a "Solar System" ? I would contact a RV Solar Company! Personally, I would NOT allow ANY of the RV Trailer Sales places I've seen install anything but"STOCK" items on our RV! Bottom line, Curtis Trailers treated us Awesome! But when it comes to custom ad-ons like solar? Do yourself a favor and have a pro in that field do it "Right" the first time for "YOUR" particular needs! God Bless and good luck.....
