Thanks for all the feedback so far, guys
I am still so undecided between the two boats.
As for the Avalanche, I know that it is more of a performance hull than the V-18. Performance is great, but I don't really fish any huge lakes that require 60+ MPH runs for long periods of time and don't know if I want to pay $3000 more for that.
In comparing the two boats at the Tracker site, it almost looks like the V-18 has a bit more storage in the front deck than the Avalanche, although it's hard to really tell from photos. The V-18 has 2 compartments vs. 1 on the Avalanche. I did notice in the photos of the 2005 model V-18, it looks like the storage toward the aft end of the front deck is now waterproof, which is a good thing. The layout of the storage looks like the same as my 1996 Tracker Pro Team 18, with regard to waterproof compartments, etc.
Also, how much room do each of the boats have in the stern for batteries, etc. I currently run 3 Group-27 Power Troll batteries and don't really want to have to change that. I use two of them for a 24 Volt 74 lb. thrust Minn Kota Maxxum and one for cranking and accessories. I also have a Guest 3-bank 45 AMP charger mounted under the bench passenger-side seat that I would want to install on the new boat. Hopefully there is room for that also.
Any feedback on these items would be greatly appreciated!
