I installed a Progressive Industries hardwired model.
It performs well, and I had questions soon after install and their customer service was great.
My only recommendation is to get the remote display version if you'll be burying the unit where it's hard to see. Mine is with my switch gear and such, under the bed. I WISH I had installed the remote display so i could see what's going on at a glance. I never thought I would want to..... never care at home after all.... but it seems in the RV, every time I plug it in I want to know.... & when it's faulting, even more need to know....
