Thanks guys for your input, I did read about Lippert and Gen-Y not being approved only the Reese.
Anyone have any info on Solar upgrade costs?
Late response here, but I've done a number of solar installs on RVs. First off, stay away from flexible solar panels. They're trash, they're inefficient, they don't last long, and they'll burn the roof of your RV. Solar panels need to have airflow behind them to keep them cool, both for them to work well and for them to last. You want glass panels.
As to cost, my current system has 412Ah of 12v LiFePO4 batteries, 800W of solar panels (200Wx4), a large inverter that will run my AC, a large DC-DC charger to charge the trailer batteries from the truck, and all of the other miscellaneous parts required. It cost me about $11k, but I did all the work myself. If you're paying someone else to do an install it's generally safe to assume that the labor will cost about the same as your parts cost.
