Different brand... Surge Guard dropped the bypass capability... and I hadn't found this forum back when I made the purchase to see what else was available...
On my unit (2014 Hurricane) - The transfer switch and converter are under the bed... really wasn't another place I could find to tie it in without running lengths of #10AWG. I have no water near the bed (water pump is under bathroom sink).
Looked like a nice install in your unit.. I may very well hardwire the next one
