[Rving Labs]

Hopefully, this post is in the correct thread instead of starting a new thread, please move it if needed.  New to this group and reading as much as I can because I am on a quest for a Newell for myself and my labs.  Budget wise I need to buy the more vintage models which I love too. This thread really interests me as I am looking at a 1997 #458, that I understand has been documented in this group over the years. I am just not proficient yet at finding all the data in the search.  More than anything I am trying to learn what are the important improvements from year to year in the late 90's to very early 2000 models? I need safer drivability and wider body, more space for me and the dogs. My husband is mechanically inclined but most times he needs to stay home to look after the dogs I don't take with me on the road to shows. 
Thank you in advance for the insights.
