There have been many different answers to this post and a lot of different advice and suggestions. We have been fulltiming for 2 years and love it. Everyone does it differently and there is really no right or wrong way in my mind. We are younger than many fulltimers (39 and 44) and we have a "home" that many don't think would be a good fulltimer rig, but it works for us and we're not looking to "upgrade". We use the same 05 Dodge 3/4 ton and 07 34' Jayco Eagle we had when we still had our sticks and bricks home. One thing I can offer is to take care of what ever you decide on and make it your own. All rvs of any kind or brand have issues. I can agree with the debt free advice. To us, that is an absolute necessity.
Like others have said, it depends on your reasoning. We became fulltimers to travel, simplify our lives, and chase dreams of what we really want to do with our lives. The great thing to us about this lifestyle is the ability to adapt into what ever we want or need.
