'91 300TE 4-matic front axles

I have one inner and one outer front CV boot going, and some grease has spun out of outer one, the right side one. No symptoms of bad joints yet--smooth, no clicking. Have to tow a boat to Florida, 1200 miles each way, next month. Would I be crazy to get split boots put on? Would I be best advised to have the half-axles rebuilt, with new balls and races as well as boots? 136 K miles on the car. Cost is very much a concern. New half-axles are $900 +, each, and out of the question. What would you do? Thanks very much---Mason
