If you can trade a 153 track and skid straight up for 162 go for it. Just change the drivers. The tunnel doesn’t need to be lengthened though it’s fine. Just trim off some of the flap. Did my ‘13 153 in ‘14 and have put on 1000 miles since with no issues.
Spent Saturday making loop from cabin around back way to anthills. Most areas have 8 ish inches but tracks everywhere. Would be nice to get one last dump before the end. Most of the day was relatively clear.
Thank you for such a detailed post with pics. We were in blue yesterday at coulees. Same conditions as you had at renshaw. It was snowing off and on during the day but had great untouched conditions.
