Most "life altering decisions" are too tough for me, but in following your link, Sharon, I think I can offer some advice on this one.
Gather up a bit of food, then lock yourself in your bathroom for the next week.
Chances are, it's just about the right size to give you a good idea of how an RV is going to feel. Okay, I'll admit the seat in the RV is probably more comfortable than the one in your bathroom. On the other hand, after three months of taking a shower in an RV, I thought my bathtub felt like the Grand Canyon. My first bath after returning home, I got lost for three days.
More seriously, I have a LOT of friends who spend half of each year on the road. They can't imagine a more perfect life, and I often envy them their comfort level. I tried it, as you know. Didn't like it. To me, it felt a little bit too much like a covered wagon. But, hey, everyone knows I'm a little weird.
