Buying new crew short bed 6.2 4x4 truck. newbie here. need opinions on my 5ver weight and recommendation for axle ratio and if a 250 is going to squat back of truck more than a 350 will. I live in Indiana where terrain is rolling. We travel thru Kentucky and Tennessee camping 20% and 80% daily driver. what would be best opinion on axle ratio and which truck a 250 or 350. thanks.
