We are almost ready to order our new FW. Love the layout of this new trailer. We are not new to camping but are trading in our TT on this purchase. Those of you that are experienced, should I order it with the Generator Prep. We now have a small Honda that we hook up on the rare times that we need it. Is it worth it to prep the trailer? Secondly, should we add the Trailair hitch and what is it? Is this something that makes the FW hitch up better??? Also, what about the Central Vacuum? Is that a good add on? Thanks for your help.
