You were serious...
And yes, you picked up on the the OP has a transfer switch at the house. So far so good. He won't kill linemen trying to restore the power (but there are enough people back feeding their homes through a dryer plug or something, they assume hot all the time).
But OP has a 7kw genset, unknown if 120 or 240. Certainly not large enough to power the whole house at once and maybe not able to power 240V circuits. SO plenty to consider or change on the house end.
On the RV end, where is the "power" you plug your cord into going to come from? The little household outlet on the outside? The RV needs what I said earlier to work to it's fullest potential.
Bad advice is one thing. Might get wet, stranded, hit in the head if you unknowingly follow bad advice about most things, save for electrical. Following bad electrical advice will just zap or kill ya right there on the spot.
OP also is assumed to be an electrician because he is a lineman.
If he was a knowledgeable residential electrician, he wouldn't have these questions.
