You sound just like I did in April when I was in the market for a new boat. I have a family of four and will spend most my time on the Spokane River, and Alberton Gorge with a couple of mulitidays slipped in there, perhaps on the Deschutes, John Day, Hells Canyon, and Salmon Rivers. I was leaning heavily toward a 143D and had an opportunity to row it, and a 156D, and it was a no brainer. The 156D is an awesome boat, especially for those with a family. The floor is a bit deeper and tubes a bit larger which makes the family feel safer. Also, with the diminishing tubes and narrow profile this thing is a corvette on the river, highly menoverable. I picked up my boat brand new from AIRE in the spring for 1400 bucks off! It was an old seriel number boat, actually a 2008 (gotta go 08 or newer for the chaffe pads), but it had never seen a river mile, and the no fault 10 year warrenty is from the date of purchase. If anything buy an AIRE boat. Look at used boats for sale, rarely do you see an AIRE with a patch, lots of other boats out there with patches.
