I don't know where that 6625 pound weight came from. Check out the pdf that I linked to. H-S lists a weight of 7990
dry with twin engines. Add 1500 pounds for a triple axle, aluminum trailer, 1300 pounds for 200 gallons of gas and you're at 11,000 pounds pretty quick.
No offense, but the Avalanche - or
any 1/2 ton truck - is not going to handle that. Besides, with a 9'7" beam that would not be too much fun to trailer even with a 1 ton diesel truck.
Do a search over at
www.thehulltruth.com on the 2600. I seem to recall there were 1 or more owners from CT who reported the poor ride. It's definitely a nice looking boat, however, and the H-S quality is good.
