New Member- This is a great forum and I have enjoyed reading it for over a year. I purchased a new r-21 tug when I really had started to look for a CD-22. The tug is great on the St. Johns river but I see some problems as I am about to move up on the Tennessee river. Think we may need a little more room or facilities as we hit longer cruises. Was thinking of pushing a small barge but Bob Austin has about convinced me to modify what I have since I can't afford to trade up right now.( in a riverfront home building project at the present). Keep up the great forum and hit me if you have thoughts on my issue. Thanks Ron
