Mike, we do have the separate inverter+ converter on our 2013 2552. They are under the passenger side twin bed. On a previous factory visit we had Doug cut and hinge the bed board so we have easy access to the components below. It doesn't have lifters as there is no framing to support them but one of us holds it up while the other roots around in there. That output cabling is what Doug tested for us in Spearfish and said it's good. We may wind up swapping out the converter at some point. We plan to add solar and lithium and were holding out to get it all done at once to make sure everything works as efficiently as possible BUT we may have to bite the bullet and buy a converter now... Or keep plugging in our smart charger as part of our site set up.
