Hello JSC168...thanks for the reply, even though delayed. I added the Go-Power panels, changed to 4 6v batteries and awaiting new MMPT controller in development from Atkinson that will fit in place of existing one. Happy with the install and results so far - we'll see if the Go-Power panels hold up; if not I will take a closer look at the AllPowers one you noted ... thanks. See you on the road someday.
Sorry should have responded earlier, been off forum for a while. My solar is not working right anymore. Those Go-Power flex panels seemed to have oxidized too much and also some surface delamination going on. I'm about to replace them with some new flex panels. There are a lot more available now, and much cheaper than the $1000+ I spent for the Go-Power ones that I got, and that Airstream uses. I don't know if anyone else had their panels go bad like mine. The newer ones I bought are black and have an "ETFE" layer surface that is supposed to be good for 25 years. https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
Also, after reading some forums, one of the important upgrades is to change to an MPPT solar charge controller. I ordered a Victron 100/30, supposedly it can handle expansion up to 440 watts, and there is a way to mount it in the area under the jump seat.

Solar panel addition follow-up
I too own a 2016 GT-EXT and love it. Mod's include a "headboard" for bed; a safe for laptops and $'s; pantry mirror for wife and small towel bar under switch panels by front door. Wife added lots of Container Store plastic boxes for drawers, pantry & fridge to increase and secure storage of foodstuffs.
SOLAR PANEL - I too want to add more and just love your simple solution. It's now been about 9 months since your post - how is it holding up? Still working and giving you the extra-off grid for the fridge and some lights? How did you plug the new panels into the existing one and am I clear you did not have to modify the controller? Would truly love to know more as we will be boon docking at Albuquerque Balloon Festival in October 2017.
Thanks, Joe Harris, Key Largo, Florida. Please see my private message to you which includes an e-mail and telephone number.
