There are very few people on here that can honestly say that they stayed within the timeframe they originally scheduled to get their conversion done and get on the road.
Don't count on parking just anywhere while you convert. You may be thinking "Oh, I only need to do this for a couple of weeks or a couple of months", when actually, it could possible end up being a couple of years.
We are in the process of converting and actually didn't really set a time to get it done, but I can tell you, that both of us never thought that we would have so little done in 2 1/2 years.
Time, illness, weather has kicked the **** out of our game plan (as bad as the plan was).
As already told....plan on having a place to put her before you buy her.
