plan b
don't really like the caravan, known for weak transmissions. i am assuming you don't have a hitch on it now. have you asked yourself what your plan b is going to be if the caravan breaks down on the way back wih the boat in tow. then you will have to find somebody with some equipment to get you home, but now you have to tow the boat and the van. just a thought take it or leave it. find someone who has a dependable truck and ask them to help you out. make it worth their while. for the money you would spend on hitch, oil cooler, and fuel i would think you could make someone a reasonable offer to get your boat home. if you were to break down in the caravan you will be back to square one only now you will have a substantial repair bill as well as a hefty towing bill. get the boat home and a good tow vehicle will come around. many folks are seriously thinking about getting rid of vehicles that dont get high mileage and as fuel goes up, there are some real bargains out there. just wanted to help you look at it from a different angle, cant help you on the ballast question-but i can just about bet there is someone that will give you exactly the info you need to know. bring tools, wire and crimpers,a sturdy floor jack, good spare, some grease, and pull over every so often and put a hand on those hubs to make sure they are not heating up. conservatively 400 miles should take you 8 hours, plan on 4 to six hours to get everything squared away when you get there, and 8 hours to get home. don't forget to bring a pair of good ratchet straps in case. duck tape and strips of old carpeting come in real handy also to keep things from getting chafed up. i pulled three boats home this year, seems like there is always something unexpected to fix, besides getting everything secured for the trip. you definitely do not want to be the guy on the side of the road broke down, or worse yet in a wreck. know your limitations, take your time and enjoy the ride. let us know when you get home and how it went dpatrickp.s. probably the best information i can give you is don't forget to include God Almighty in your plans, like Ollie North says"he doesn't always guarantee a smooth ride, but he promises a safe arrival." God's been good to me! and i want to give Him all the credit.thanks
