I have this setup at my house. The coach has a full hookup (50 AMP) beside the house. If this really interests you consider hiring a licensed electrician and passing whatever the local codes are for your area. This is what I did. It cost more up front, but one does not run into the concerns mentioned in the previous posts.
I did this in 05. Everything has worked as advertised.
With my 7.5 KW generator I get about 60 AMPS total output (30 AMPS on each leg). This is fine for the 120 VAC needs. It will not do any 240 VAC appliances (HWH, HVAC, etc.). For me, this is okay. For HVAC and HWH, we have what we need in the coach.
