I just posted a similar question on plowsite. Has anyone had any experience with a GM 3500hd (#15000)gvw with the monroe 4x4 conversion? I am thinking about taking a look at one that is for sale and not sure if this was a successful conversion or if it was plagued with issues. Seems like there could be a problem with front end wear or if the automatic transmission could handle the job. I would appreciate any info good or bad.
