For me, last season was the BIG upgrade! We went from the 33' 5th wheel toyhauler to the Class C Jayco with enclosed trailer.
The new items for this season are...
The Go Power! 170 Watt solar panel with charge control mounted inside the coach
The Go Power! AGM-100 12V Battery.
We've used it twice so far for short weekend trips. It's worked out great so far. We can't wait to try it out in the dunes for a nice 2-3 night stay. Then I will determine if I need more wattage to support my families needs for the weekend.
The Jayco came with a 1000 watt inverter, I decided to keep that and we'll see if we need to upgrade the inverter next year...Maybe the 3000 watt unit LOL!
