Wow thank you for all the great information. A lot to consider, it looks like I am trying to bite of more than I can chew lol. There will be 4 of us that can drive, but no none of us has ever driven and RV. My husband and I have driven larger uhaul trucks, not sure if that is even a comparison. This is why I wanted to get as much info as possible.
I think driving a U-Haul is a very reasonable comparison. I generally find my class C is generally similar to a loaded U-Haul with slightly better visibility to the sides and the back and a slightly more comfortable driver's seat (but there is still some room for improvement there).
With four drivers, it's not out of the question to go from Florida to Seattle in maybe five or six long days. You would not get to stop and stretch your legs much or see a lot in between save through the windshield, but it should be doable if rather less than pleasant. Besides that, Vegas to LA is a pretty full day's drive, LA to San Fran a full day, San Fran to Portland another full day...so at least three or four more of the days just driving, not touring.
Frankly, if you're looking mainly to see the cities you list, an RV is not the most practical way to travel. Driving a motorhome (or pulling a trailer) through city streets is quite stressful, and finding a place to park it far from easy. You'd probably end up staying in a rather urban campground, which often means something like a large parking lot with RVs crammed in more or less like sardines, and taking mass transit or taxis or Uber cars wherever you go. Where the RV really shines is for seeing more out-of-the-way places. (Much of Colorado would be splendid in an RV, on the other hand.)
I might look into Amtrak rail passes for the trip (and hotels or motels in the cities). They have some multi-trip ticket deals that are a pretty good value, and on some of the lines you get to see a lot of great scenery. A train also gives a bit more room to stretch one's legs while en route, though less privacy and comfort at night unless you fork over for a bedroom of some sort or another--which is a pretty steep forkful of coin, admittedly, but it still may well end up being a less expensive proposition, and I think a lot more enjoyable for all.
