I would agree with a lot of posters here. You are talking about a larger family on longer trips with a shorter coach. The equation does not really add up. You’ll need to at least go 34’ to get some decent space storage and bunks. You still aren’t really compromised on what sort of places you can get into. You did not mention a budget but if you can go DP for long trips I think you would be happier. Thor makes a nice DP bunkhouse , the Palazzo 33.3 and can be had for $140-150k. Queen bed, 2 bunks, queen sleeper sofa and queen drop down bunk. That thing would sleep 10 if you had to – 8 comfortably. But again it comes down to budget. You’ll get better MPG in a new short DP too. Many owners of Tiffin Reds, FW Excursion and Thor Palazzos claim double digit MPG. Cross country that could be hundreds if not a thousand or more in fuel savings. Hard to beat the compact coach on a Freightliner chassis with a 300HP Cummins with DEF for maximum MPG. And you may want to rethink your toad. That long of a travel I am not sure I’d be without a dinghy. My rule is, better to have it and not need it, than need it and not have it. Otherwise how will you do sightseeing, shopping, dining out etc? Heck a quick trip to the store becomes a huge hassle without a toad.
