As we've been on the road, nearly 10 years, I can envision the day we'll not feel comfortable towing and backing up into tight spots anymore. We'll trade the F450 in for a mid-size SUV. Seems like the best of both Worlds.
We looked all over and finally two years ago, we bought a lot within 2-hrs of the majority of our kids. That way, we can stay Independent for as long as possible and stay Rent Free when we're visiting long stretches. Made more sense than buying a Lot or Home in ID, OR, TX or FL, a long drive away and where we don't care for the Countryside or their Climate year round.
