I owned a 182L from 97 thru 2001 when I went to a T310Q. I put 1100 hr on
the 182 in 4 yrs and I think I'll go back to a 182 when I get rid of the
310. The 68 model has the highest service ceiling (I believe) at 17,900. I
dont think mine would get to that but I did have it up to 16,000 once
crossing the Rockies. I had a modest panel and felt very comfortable flying
IFR (IMC).
