My dislike of the Avalanche comes from the one they got at BPS in Grapevine (Dallas). Around the back corners, the rub rail is "poochy" because it wasn't designed to make that tight of a curve. Again, this is the showroom floor. If it isn't right on the showroom floor (this is their EXAMPLE product), why would I expect better when I take one home? Of course, I'm jaded in that I had a bad boat buying experience at that store, and I own an Xpress. Maybe I was just looking for flaws.
The Tundra is too short (from specs... haven't looked at one up close). Everything about it looks great except the length. I believe tracker's website talks about the 16' model as being great for guides. If I'm taking 3 or 4 of my best friends out for a guide trip, I ain't expecting a 16' boat!
I have a friend who guides for catfish in a 20' Alumacraft flat-bottom boat. Now, THAT is a guide boat... it ain't pretty, and the metal could be thicker, but there were 4 people in that boat and we weren't in each other's way.
