I am seriously considering buying an 06' C4 Avalanch. Boat looks clean with loads of options. I am coming off of an 04' Sanger V210. Loved that boat but it was destroyed when the shop I left it at last Fall to get winterized caught fire and burned to the ground...bet you haven't heard that one yet. In all, from what I have read on this extremely informative forum, it seems like a solid boat. I was looking for feedback on anything I should pay particular attention when buying. There are 450 Hours on the boat and I am buying from a second owner. He has all the original paperwork and all service records. I am buying long distance and shipping and am going to have third party mechanic do an inspection. Looking for reliable family boat that can do a little of everything. Surf...of course, tubing, kneeboarding, wakeskate and every once and a while dad likes to bust out the slalom ski and do his best Andy Maple impression. I know the C4 is no course skiing DD, however, is the wake decent enough to long line and have some fun on a slalom ski? Kids are also getting into rec skiing. The boat does have the adjustable trim tab. As far as the hull goes how does it perform in rough water? I boat on a high mountain lake that can get pretty rowdy quick. Also was wondering how big the cooler is...functional? Lastly boat has heaters, kind of a big deal because I live in mountains and I think this will really extend the season. Any issues with these that I should be aware of? Thanks for your help hopefully look forward to being part of Centurion Crew!
