First of all, I do not want to keep our house. It's two big for two people and we never even go upstairs...EVER!! So it's rediculous to keep something that we are paying and enormous mortgage on when it's not being used! Secondly, yes we know how much we will save, and yes it will be extremely worth it. That's the whole idea..to beef up savings and our 401k and pay off what little debt we have and save save save. Thirdly, even though we work in the same office building we rarely see each other. My husband and I have been together for 34 yrs. We are best of friends. We get along extremely well. So that is a mute issue. Fourthly, we have camped more than just weekends. We have gone on exteneded trips alot and we know we like each other and living in our camper. Someone said to me one time. If you dread going home, then you know you are a full-timer. I dread going home. I want to live in my camper. As well as my husband. So I really don't think any of the concerns listed above pertain to us. But how are we to know if we don't try? If it doesn't work out, we'll buy a townhome or a condo somewhere and then decide what to do after retirement.
