"RoyalRaven"......Out of curiosity, why do you want the portable unit?
Personally, the easier it is to set up camp and pack away, the simpler RV life becomes. With the portable unit, you're having to drag it to the power pole and then worry about securing it. I know a lot of people do it, but it just seems like extra work. If you intend to take it with you when you sell the coach, just remove it.
