Don't do it, Don't do it. You will never go back, you will never return to any place either. You will find yourself on the road or in some camp ground making new friends and going places that you have never been. You will end up seeing America and basking in it's beauty and all of things and places that you read about as a kid. History will come alive and so will you. Don't do it.
Well welcome to the site and I hope you learn a lot from us before and after you make your purchase.
Now as far as the 35F, I have a new one 2014 model and really like it. But as far as full timing it I would go to different model that has a washer/dryer and of course 1 1/2 bath. Its just me, the wife and the Pugh but the Washer /Dryer would be real nice for long, long trips.
Whatever you decide on, before you decide. take a good look at what the unit looks like with all the slides in, in travel position. Check for things like, access to the Fridge and the bathroom. Also check for access from the entrance to the drivers\passengers seat. You would be amazed at the lack of egress to them on some models (33C) with the slides in.
Enjoy the hunt and again Welcome to our world.
