Good luck with any/all of your decisions!! iF you don't want the 'hefty' 4x4 SMB puts in, I HIGHLY recommend Quadvan to put the 4x4 unit in….it essentially a 350 4x4 unit vs. SMB's 550 (to be VERY BASIC in how it was explained to me…some of the experts on here, and as you know EXPERTS, could do a much better job explaining) I know you said no to 4x4, but if you can swing the extra $'s and aren't necessarily going to go rocking it, it will get you in , through, and around many places a 2x2 could (maybe) go, but with great hesitation and maybe eventually abandoning what could have been an awesome place very very few people visit, let along photograph. 4x4 is a great piece of mind, and try checking out Pschitt's gallery, a motivation to go places you might only DREAM of!!!!!!
