I have a 1995 Pleasureway on a Dodge Ram 3500 chassis.For a number of years (pre about 2003) Dodge made their 3500's with a rear track (distance between the rear wheels) 4 inches narrower than the front track. Result was a tendency for the van to "wander" on the highway, particularly on roads where there are double ruts from large trucks. Many people, me included, added 2 inch thick steel spacers between each rear drum and the wheel to bring both front and rear tracks into line. I haven't heard anyone make any negative comments about the result. Comments indicate huge improvement in handling ease - and that's my experience. I got mine from Fred Goeske in California. He seemed extremely knowledgable of the problem, paid careful attention to my particular needs (wheel bolt pattern, stud diameters, etc) and shipped me exactly what I needed. Installation was very straightforward - just follow Fred's recommendations for torquing the nuts. You can Google wheel spacers or go to
