Congratulations, definitely post up some pictures once you have them. I think you'll find the 430 HD a much more versatile boat than the 340 airdeck. With the 430 you'll easily be able to fit 2 adults plus camping/fishing/hunting gear for a few days. That would have been very difficult with the 340. Also the hard floor will be much more durable than the airdeck, especially for carrying gear. The boat and motor are still a manageble weight for 1 person to set up & take down with the use of launching wheels.

One more thought, if you are taking a trip with another adult and yourself along with a fair bit of gear (including extra gas tanks), you'll be glad that you didn't go any less than 25 HP.
