We have the Lippert One Control (
https://www.lci1.com/onecontrol) and we love it. As far as "remote" - we have the corresponding app on our iPhones and iPads so we can do it all from any location inside or outside near the fifth wheel. I'm not really familiar with the Lippert Linc system so perhaps I'm speaking out of school here.
I suspect you're going to need to have that installed during the build. I'm not sure they could run all the wires from the main control center to retro-fit it, but perhaps they could. I think it would certainly be less expensive to do it during the build.
Again - I don't know how familiar Lippert Linc and Lippert One Control are.
