I've had both 3500 single tire rear axle and dual tire
rear axle.. I prefer the dual all day long.. as to
parking I've never had any problem parking the dually
but I MIGHT have to walk a few extra steps.. but if this
is your daily driver then the single tire works fine..
specially at that weight... but I sure think the
dually looks WAY better... I drove my dually to work
for a while and never had any problems parking
