I need to purchase some Dana 60 shafts. I should stick with what I know and buy cromo U joint shafts and CTMs, but I really don't want to roll the dice on Yukons and while Foote stubs are available inners don't appear to be. The sale on CTMs is over and I cannot justify $3700 for those. I am considering RCV. They are at the top of my budget range, but if they are the best I can do for the money I am in. How are they to maintain, and what do you give up as far as tuning radius? Do they seal well or do you take them apart clean and re grease after every water crossing or mud hole?
