Hi Bill and El,
We tried both (boating and RVing) at the same time for a number of years, towing a sailboat behind a motorcoach. Early on, it seemed like the best of both worlds... it quickly became more work than enjoyment. The inconvenience of not being able to pull into most campgrounds, or even stopping for lunch - you have to plan for that with nearly 80' of length. Not to mention having to drive separately - we needed a daily driver and something with some size to launch or separately tow the sailboat. Over the years, we did manage to simplify things with a small catboat and a Class B campervan.
These days, it's one or the other for us.
Bill and El, you have to understand that you two are the exception, or perhaps the "ideal" for minimalism. Don't get me wrong - it was your influence that convinced us that we could be happy in a C-Dory. But, happy in a different way from you two. We take more than three outfits; we like to have a shower everyday; we enjoy TV and satellite radio; and we will always be traveling with a furry family member. We have been together since we were kids, but we both like to have some elbow room. Had we bought a 22, it is likely we wouldn't have been as enamored with C-Dory cruising as we have. The 25 suits us. For us, it is our idea of minimalism. :wink:
I think everyone has their "least common denominator" for creature comforts... yours are below the threshold for some of us. But that difference doesn't make either of our styles wrong. It just means that one has to determine what best suits their need, and make their buying decisions accordingly. You have selected the boat that works best for you, as have we. And neither of our boats have the amenities of most motorhomes when on land.
Yes, we enjoy RV parks. And marinas. And quiet anchorages. We have stayed in campgrounds with our boat and in marinas (with RV sites) with our RVs.

We find Lake Powell to be absolutely spiritual; but, we also enjoy the touristy feel of Lake Havasu or the casinos in Laughlin. You look at the mountains ringing the water and see layers of Kayenta Sandstone and evidence of recent volcanic activity, I see the color temperature of the light as the sun slips past the horizon. And, we both find the places magical.
When you wrote of your trip to Alaska with 5 people in your 22, my first thought was: how can they do that without wanting to kill each other?? But for you, it was a wonderful trip.
Completely different perspectives.
When the questions of "boaterhome" and "Lake Havasu" came up, I tried to give our friend RetNavy our honest perspective. With over 300,000 miles in RVs, we also have different perspectives there.
I have to chuckle. While writing this post, Joan said, "You should probably dump the tanks." How's that for timing? I went outside, pulled a lever and turned a valve to flush the black tank; then closed a lever and opened two more for the gray tanks. Easy, 'cause that's the way it was designed. But, pull up to a marina pumpout station with our 5th wheel, and it ain't gonna work!

They really are two different worlds. There is an ease to RVing that we enjoy; there is an escape to boating that we enjoy.
How wonderful that we can all approach our passion for these boats from different perspectives, use the boats in different ways, and enjoy them, and the places they take us, to the max. :thup Just like the boat, our RVs have always been "escape pods."
Best wishes,
Jim
