I have a 2015 Tuscany 40DX that is quite power hungry being all electric coach with a large residential frig (108 watts all the time.) I bought a CNBOU 40 amp MPPT controller in Quartzsite last February thinking of going solar. My 40DX had 10 gage wires up to the rear AC. I got 4 Canadian Solar 180 watt 3 year old hail damaged (none showing) for $95/each. I wired them as 2 in series in parallel with the other two so about 10 amps max in the 10 G wires. Here in Northern CO the first day of fall I was getting 33 amps charge into the bank of 4 GC2's. Pretty happy with about 500 watts delivered from 720 spec'd power from the 4 180 watt panels. Total cost was a little more than $730. Hopefully my solar will keep up with the static drain (maybe 150 AH per day) from the coach? Happy camper!
