Good idea Scoti on the extra weight for testing.

I've driven a few trucks with coilovers on the rear all right about 1,600 lbs for rear axle weights. The trucks with rear mounted tanks ride very well with 200 lb./in. springs. If the fuel tank is mounted ahead of the axle like the '73 & newer GM trucks I prefer a little lighter 175 lb./in. springs. The added leverage on the suspension makes a noticeable difference.
