182 to 337 transition; wise?

[Mutombo]

I have about 600 hrs. (IFR cert.) in my own '79 182Q (1600 TT) and am possibly interested in moving to a 337 (my wife doesn't know it, yet - so this may be a dead deal already). We live in Colorado - no mountain flying, but frequent Kansas City (550 miles), Wyoming, and New Mexico (1000 miles longest trip). What about a 337 -- or is this "muddy" thinking? Can you refer me to 337 owners in Colorado, Nebraska, and Kansas that might be able to help me in this decision process? Thanks.
