Best year for used argo

[garretttpe]

No advice on the ARGO but you should look closely at making a set of open grouser tracks, should be some good info on here about Alaska/tracks

I looking to buy a  used argo eight wheeler.  I know they have made improvements over the years and would like an opinion on the year the last best improvements were made and what years to stay away from.  I will be putting some type of track on it if it does not already come with it.  Looking at riding in Alaska soupy swamps. Thanks for any info.
