Hello to everyone, I hope you are having a great summer. My wife and I are planning to retire and travel the southern USA in the winter and Canada in the summer.Our initial search was for class C's but we quickly realized they are too small.We have narrowed our class A gas search down to the Thor Daybreak.........Georgetown XL.....and the Tiffin Allegro's. I am over 6'3" so I need high ceilings. Any help and advice you have to give would be greatly appreciated as we are brand new to the RV world. Is one of these coach's superior to the others? Thanks for your time..........RV Rookie Ottawa.
