We (two of us) did just that two years ago......a month off and toured western national parks. We pulled a small 4x4 toad (with two bikes hanging on it) which was very useful for getting to hiking spots and getting around Yellowstone (we drove 100 miles in one day at Yellowstone). Our only regret was not taking two months off. We never felt cramped in the RV. We loaded up heavily on food we pre-fabricated and froze (pre-cooked our bacon, etc) so we made the most of the space available and minimized grocery stops. We have no problem with storage in the Navion. We did carry some stuff in the toad (like a 20 lb LP tank). We are much more outdoors oriented so we almost always cook outdoors and the TV goes unused. We had laptops and used iphones for hotspots for internet.
