Hello and thanks in advance for any info. I just picked up my 2015 Nash 25c to replace my 2010 22h! (Which is for sale!) I had the dealer install two 6v batteries and roof mount a Zamp 100 watt panel....
Yes you can!! I have this Renogy 100 watt suitcase with separate built in controller. It works well with the roof top solar on my TC and TT. It is quite interesting to see it gain 4 Amps by pointing it at the sun vs laying flat!!! Amazon for about $270, free shipping!!
