5th wheeling, any regrets????

We are exploring our options when I retire in January. One of them, the one I am most geeked about is purchasing a fifth wheel rig. We have a park home that we can summer in in Homer Michigan. What we are thinking about doing is selling our main house and purchasing a fifth wheel rig and spend our winters traveling.
This has probably been posted before, but what I would like to know is what are the pluses and minuses about this lifestyle?
I understand that if we don't like it we will have to probably take a big hit on selling the rig.
Is there any places that will lease a rig for a year?

Thanks in advance for any help in this matter.
