I purchased a 07 Lazy Daze (LD) Mid Bath (MB) four years and a few months ago. It some looking and I wound up flying to California and driving home. It was a solo trip because my wife could not get off work.
I second joining both The Life with Lazy Daze RV ( https://groups.yahoo.com/neo/groups/lifewithalazydazerv/info ) and SE Lazy Dazers (https://groups.yahoo.com/neo/groups/se_lazy_dazers/info ) yahoo groups.
We found our RV on the Life with Lazy Daze but I found a lot of support in several groups.
I taped the top seams of the RV when the RV was 5 years old before the existing seams needed resealing. The factory owners manual is very helpful and while they recommend periodic inspection I do recall the factory not saying to reseal the roof every two years. The factory is not a fan of Eternabond Tape because it is so difficult to remove.
There are enough improvements in the Ford e-450, as well as with small things the LD factory changed, that if you can get a 08 or newer.
All the talk about roof sealing points to the biggest issue any other RV, look closely for leaks.
