a year of van ownership. specs 1990 E350 XL package, 460 FI, e4od, dana 60's front and rear with leaf springs, dual tanks, arb rear locker is the good stuff, or was. Did a waterpump, major tuneup and all fluids changed and went camping about 10 times. The suspension was awful, any bump or ripple made my wife cringe. just finished a 1252 mile road trip (10.25MPG average) including a quick stop at Agile OffRoad to get a new TTB installed, by far the biggest improvement made to date.
