I had the same feeling of the front end being too firm. Aside from going to an rmk front end which will cost you, or putting softer shocks/springs on which will also cost you, you can go the cheap route and put some older softer springs on. I went with a set of genII springs, but they don't just fit automatically, I had to slip the genII plastic support inside the walker sleeve to support the springs, then set preload to near max. Still not as good as the narrower rmk a-arms though, that's what I ultimately want.
As far as the tank, check out the trail tanks website they have a bigger one
When would you ever want 16" of ski lift??
