My main reason for solar was to keep the camper charged while sitting in driveway (with refrigerator running on propane). 200w on the Wolf Creek did that just find with my two 27 series 90ah AGM's last year.
But new rig has different shaped roof with I think will allow for the bigger panels. (and I moved my AGM's from WC to new camper)
Plus this year we plan on doing some boon docking in national parks. At least until AC season starts up full swing.
