We have a 1998 Dodge 1500 cargo van in our rental fleet with a 5.2L in it. Not really comparable for MPGs as ours is a big empty box half the time, where as yours is always full of all the furniture/appliances etc. The injected 5.2L is decent in reliability, but the first thing I would suggest doing is finding out what rear axle ratio is in your van. If it will only be used for highway trekking, then depending on what ratio you have now, it may be worth looking into changing it for something better suited to highway driving. Unfortunately the rear differentials in these trucks are prone to wearing out bearings, so if yours is already noisy, having the ring and pinion changed while the diff is apart for bearing replacement anyway would save you some cost on labor.
